Melatonin & Diarrhea???

I started melatonin (10 mg) after a nurse friend told me how much it had helped her. I started taking it about a week after my bout of diverticulitis cleared up. I almost immediately developed diarrhea and loose stools along with serious cramping. I was also waking up with a headache every day. I thought I had not recovered from the diverticulitis, but am now wondering if it is the melatonin. I have severe cramping on the left side, but doesn't feel the same as before. Hoping it is gas. Have been off the melatonin for about 5 days. Diarrhea seems better, just cramping now. Does anyone have suggestions on how to get rid of the gas? At least I hope it's gas! Have tried Pepcid, but doesn't seem to help.

I swig activated charcoal slurry a lot. I buy a large container of the activated charcoal powder and mix it with water and put it in a bottle. I think I have one in my bathroom and one in my livingroom. Good stuff.

Followup:Maximus49: Started taking 5 mg Melatonin on 5/3/218. Melatonin worked great for sleeping but after 3-4 weeks developed loose & water stools. This developed to full-blown diarrhea after a month. Went to doctor on 7/16/2018, who asked for stool sample of watery diarrhea- not solid at all. Ever try to do that? nearly impossible. Looked up melatonin symptoms on HealingWell.con on 7/17/18. Stopped taking melatonin 7/17/18. Many rubber gloves later, got a sample which was tested negative. 7/28/18, Diarrhea
stopped. Normal bowel movements for first time since about 5/28/18 (60 days) and first normal BM's since stopping Melatonin on 7/16/18(12 days to return to normal).

Melatonin REALLY should have a large warning label about diarrhea.

First of all... this system is weird. Anyway, regarding the MELATONIN & DIARRHEA issues.. they are 100% accurate and true. Some people may not experience the watery- explosive diarrhea right away or at all, but it definitely kicks in and kicks your butt! No bueno. Like.. emergency blow-outs with mad-dashes to the bathroom! Not cute. I legit thought am I dying, do I have IBS, do I have colon-cancer, food poisoning, the Flu symptoms or what?!?! I was just about to go see the doctor to get the bad news (well, at least that's what I thought) then I prayed and thought... I can't be deathly ill, I am healthy and eat right. I thought.. gosh I am having such nasty-smelly Diarrhea, I am probably losing all my vitamins and nutrients. Ugh.... Then I thought... hmm... vitamins ? I don't take a whole lot, and I realized I started these issues when I bought the3 mg- Blueberry flavor gummy melatonion supplements from Walmart. Then I decided to do some research and find out further details of my issues. It is embarrassing to ask others or bring it up, so I kind of just waited these symptoms out to see, if indeed it was the melontonin. Sure enough, the deeper I read-up on these symptoms (which aren't reported or written under SIDE EFFECTS/ Symptoms for Melatonin), THEN, I FOUND THIS LOVELY WEBSITE. I read every single sad story and experience. I can relate to most of them! I even thought... gosh.. How am I going to travel and be out and about, if I have to run to the bathroom with watery-bowel movements so often w/ hard-core diarrhea?! Like that's not gas or just feeling bloated.... it was on the verge (the verge of starting a blow-out!) GOSH... so gross & embarrassing (and noisy!) lol. I always had strong whole- healthy poops and the last 3 weeks since melatonin... completely changed for the worst. So, super glad I read these comments and put two & two together. I believe God gave me the wisdom to realize what to stop taking. LOL. So weird.. never had any weird health issues like this and glad it's only temporary and something I can change and improve. STOP TAKING MELATONIN, DRINK WATER, EAT HEALTHY AND WORK-OUT DAILY! They really need to include bloating, gas, bowel irritability and diarrhea symptoms may occur. Thank you for taking the time to read, understand and make your own personal changes. *must note, melatonin does put you to sleep peacefully, but risky with your bowel movements, etc. SAY NO TO MELATONIN. :-/ -S- 9-27-2018

Hello fellow melatonin users, this is my first ever posting on any subject but I had to weigh in on the nightmare this supplement has caused. Like most I've had massive diarrhea after probably 3mos taking melatonin every night. We don't need so much melatonin and I think it's our body telling us. Since stopping I'm experiencing withdrawal like symptoms and not able sleep. Oye. This too shall pass

Hello all, normally optimistic writing to say I'm back to optimistic since the melatonin is out of my body. (Both my doc and naturopath don't think melatonin would cause diarrhea) Sleeping like a baby drinking Nighty Night tea. There is hope...
