Headaches While Doing The Master Cleanse

Here’s a question about one of the more common master cleanse side effects – headaches.

I completed the Master Cleanse yesterday. I am so looking forward the the soup!

I had a headache that seemed to start in my right ear and go down my neck. I would come and go but I seemed to have it almost every night. It became very intense when I stood up from bed. I can actually still feel it now. Will it go away? Do you know what would cause this?

Other than the headache the Cleanse was wonderful. I lost about 12 pounds.

Thanks for all the information.


Headaches usually happen early in the cleanse, and for most people go away after 3 or 4 days. The severity of the headaches varies from person to person, but there are a few common factors that can cause them.

If you drink a lot of cafien you might experience headaches when you do the master cleanse because your body is going through a withdrawal of sorts.

If this is your first time doing a detox diet you’re likly to experience headaches. In the short time it takes to do the master cleanse your body will go through a massive internal cleaning. This is a good thing, but it can be uncomfortable because years of waste that’s been dormant inside your body is now being ushered out by your bodies cleansing mechanisms.

Stress can also lead to headaches. Like I mentioned above your body will be taxed by the master cleanse so try to not to push yourself too hard.

  • Good info, especially the wheatgrass, gonna give that a try soon. Been doing the MC twice a year for 12 yrs now. Glad this site is here. Learned a few things in those years and would love to share. Thanks for the cheat sheet.

  • I’m On day 3,day 2 was the worst my headache was brutal! Day 3 has been great i’m sure my headache was very intense because I’m a BIG coffee drinker 13 cups @ day ;(
    I’m going to do my best to do the diet for 6 days.
    good luck everyone.

  • Day 1 – an entire day of migraines and vomitting! Caffeine withdrawal Im assuming.
    Day 2 – I did the SWF and that went well. Still have a headache and feel Nausea….hope it goes away soon! My system must be a mess inside

  • I am on day 2 of th MC and I have this terrible HA, besides that I feel fine.

  • I am on day 5 and headache is really bad…:( My biggest problem though is that I can’t sleep!!! Any suggestions?

  • I have another question for everyone – are you allowed to take prescription medication while on this Lemonade Diet? Has anyone else had this question or heard anything about taking meds?

  • So I started this morning for day one, couldn’t stand the drink, but managed most of the day until the headache came. It was horrible. I felt so sick already and realized that I have such a busy week ahead of me and weekend, so I had a cup of coffee and a rice cake with peanut butter and my headache disappeared shortly after. Now I’m reading all your comments and see that the headache comes with the territory and you have to get passed it. I will try again next week and hopefully will be able to make it. I wish I liked the drink more. You all are amazing for being able to stick with it for so long. How many glasses of the lemonade are you drinking? Is anyone feeling weak or lightheaded? Are you able to still do your regular exercising or daily routines? Support is definitely what someone needs during a detox.

  • I’m just completing day 6 of my first cleanse and this evening was the first time I felt like I was going to break. I think it’s because it’s Friday night and I’ve been in the practice of splurging on foods that I like when I start the weekend. I have lost 10 lbs. so far and for most of the MC I have felt strong and committed to completing it for the sake of my health. I’m going to bed early tonight and think about the many reasons I went on the cleanse and recommit so that I can make it successfully to at least day 10.

  • I am on day 1 and peeing every 20 min LOL hoping to do 14 days well see i was eating about 2500 cal a day gained 45 lb since october ( we moved to MN from AZ ) stressful! Plusa i was running oevery day and i havent been since, we got up here in oct- hoping this will give me some jump start to get back in shape!

  • Entering Day 3 of the MC and I have a crazy headache hopefully it goes away. Other than that, I lost 3lbs so far and my cravings aren’t as bad

  • Day 14, eeeeassssyyyyyyyy 🙂 roll on clear tongue, i’ve commited that if the clear tongue takes ten days or ten weeks then so be it, i’ve spent thousands through the past 5 years and done every extreme protocol in the book to remove symptoms only for others to appear shortly after. This is the final straw.

  • Day 4! Getting ready to wake up and do the worse part of the clense…..swf. I think I cook more on the clense than I did before. Going to restaurants, the smell is intense, so I stay away and just cook for my family. Work isn’t that bad, I’m always walking the floor in retail, so I have very little time to think about food or sit behind a desk and make my mind wonder. This is my second time and for some reason it seems harder. And…..organic lemons in the winter are EXSPENSIVE! .89 cent a lemon. If your thinking of doing the MC, don’t let anything deter you from starting. New year, new you!

  • Day 3 coming to an end. No real issues to report. I drink a lot of water so feeling sort of bloated right now. going to drink my night time laxitive tea and wake up earlier tomorrow to do SWF. The affects of SWF have taken as long as 2 hours, so hoping i can get it happen faster. Good luck everyone.

  • 3 day for me and already lost 5 pounds .. i just drink the mc drink and not the salt water ..im still having great results … some cravings and slight headache not tho want to do atleast 10 days but if possible i wana go up to 30 !

  • Day one of the MC. Hunger wasnt too bad and the lemon drink helped take the hunger pains away. Did my first salt water flush this morning….little advice….dont trust a fart and stay close to the toilet! Too make the salt water fluch easier I put one teaspoon of sea salt into about 4 oz of warm water, pounded it back then chugged the additional 28 oz of warm water. I dry heaved and gagged but managed to keep it down. Going to the gym for a stretching session followed by a long steam to help with the detox. I do have a massive headache right now and HOPE it goes away after a couple days!!

  • On Day 4 now and feeling really good. Had a headache on Day 2, but since I started my MC on the weekend, I just ended up staying in bed a little longer than I typically would have and the headache eventually went away. So far I have lost 6lbs and counting (yeah!)…..will hopefully make it to 18 or 20lbs on Day 10. Self-control is definitely the KEY….wish me luck and stay strong everyone!

  • I am on day 8 and have experienced no hunger or nausea, but I have a headache that feels like I haven’t had enough sleep. That tired dull feeling. I really think it is due to dehydration, as I haven’t had enough water the past two days. I am drinking more now so I hope it subsides. I have lost twelve pounds so far.

  • I’m on day 2 of MC; I have a headache and have not had a BM since yesterday morning. I will drink laxative tea tonight and do SWF in the am.

  • Jusy started the Master cleanse. I tryed the Salt water flush wasnt that bad. But felt like I wanted to throw up and I felt tired. Fix the drink it wasnt that bad either. I am looking forward to 14 days going strong.

  • I am on day 3 and I have not had a bw since yesterday morning, I am just wondering why I have not poop like they say I would.

  • I’m on day 4.I started having a headache last night but I’m sure it will pass.I’m still craving food, but Im staying strong.The swf is doing wonders.I’ve already lost 5 pounds..yay me!I had a dream that I ate bacon and broke the fast.lol..Get thee behind me satan.Lol..but you guys stay strong.You know you owe it to yourselves 🙂

  • Day 6 and my head is aching. It’s day two for the headache. I’m reading its a part of the detox. I am a big coffee drinker so maybe that’s my issue. It’s discouraging but I’m going to push forward. I’m not hunger but this headache makes me want to have a cup of chamomile tea and go to sleep.

  • This is my 1st time. Morning of Day 3 for me. I have had a headache since the night of the 1st day, the 2nd night the headache was the most intense, like a really bad hangover, I drank lots of water and had the wife give me a neck massage before bed, I woke up feeling quite a bit better and now I am doing my SWF. I am using 2 teaspoons of sea salt to 32 oz of water. I didn’t work the first day but on day 2 it did and I am sure it will today. Good luck everyone.

  • hii day 2 in my MC and its my first time to do such crazy diet
    i have lots of cravings but im still strong. The Headache is killing me right now I think its caffeine withdrawal, or maybe i have a lot of toxic to expel. I think I need to drink more water…
    8 more days to go 🙂

  • I am on day 3. I’ve had a headache since yesterday. I haven’t done the salt water flush yet. I will do it after I finish this comment…lol I think I need to drink alot more water. I dont really have any food cravings anymore. I feed my cravings by preparing food for my family…sounds weird but it works for me. What can I do to get rid of this headache? How long is too long to stay on this diet. I’m wanting to go full force since I have finally after years of trying it, have gotten past day 3. HELP ME!

  • Hi Ali-

    I just read that for the salt flush it is:
    1 teaspoon of sea salt
    25-35 oz of filtered water

    Good Luck….I just made my first batch….Tomorrow will be Day#1 for me!


  • On day one of MC!! Hoping to be strong and get all the benefits out of this since it’s not going to be easy! Can anyone tell me how much salt to use for the flush? Is it a full glass of water?
    Thank you!

  • I’m on day 3 of MC! I’m super proud of myself, I have resisted many food temptations, came home last night and my family was eating geppetos, thought I was gonna DIE but I drunk my laxative tea and went to bed! Plus I work at Sams Club and they have free samples of food all the time smh its been a struggle but I’ve pulled thru and I believe I can make it 10 days. I love getting on here and reading other stories, its a great inspiration

  • This is my first day on the master cleanse. I was wondering with the swf, do you add the salt to the water or do you take the salt & drink water afterwards? I have a silly question as well, when it says you can drink herbal tea with the lemonade…does it mean mixing them together or can I keep them separate?? I’m very excited I started this today, can’t wait to reap all the wonderful benefits from it 🙂

  • Day 5.5 lotta craving but still goin strong!!

  • Day 3!! not bad so far. Self control is a KEY!!

  • Im on Day 2 of my cleanse. So far so good. I do feel hungry here and there but i drink more of the water and keep myself busy to get mind off food 🙂 Hope I can make it to 10 days!!

  • Hi! I am on day 2 of the cleanse…I am drinking 60 oz. of the lemonade, doing the swf 2 times a day, and drinking water in between…I have had a headache but expected that because of my previous caffeine consumption…I haven’t had a movement yet so I am concerned that something isn’t working correctly…does it take a couple of days to kick in?
