I stopped my melatonin usage on Oct. 13th. By about 5-7 days after that, my diarrhea subsided and I have not used it since. Finally back to "normal." I don't imagine I'll ever use melatonin again....
Very happy to have found this thread. I started taking ZZZQuil Melatonin in August with no issues. I was not entirely sure how long I should take it though, as everything I've read said long term...
