No one seems to know what causes leg cramps and I have used every vitamin, mineral etc. and have had some relief until lately. Now that I'm on the melatonin I seem to be experiencing them frequently (nightly).
I take 3mg (time release) of melatonin every night and sleep great, but wake up with severe leg cramps every morning. Severe meaning I can't walk for an hour and need to stretch, hot tub and down 2 advils before I can start my day. The cramps get less during the day, but don't stop. This has been going on for 3 months and I have tried many solutions. No joy. After seeing your post, I am going to try taking no melatonin, and taking a magnesium instead. I'll try this for a few nights and see if there is any change. Will report back if there is an improvement.
After having some really severe leg cramps I was looking around on the internet and came across these responses. Only other med I take is lisinopril blood pressure pills and occasionally heart burn pills but not days or weeks on end.
About two days after I stopped taking the melatonin they all but went away - a week and running and not even getting the foot cramps I was before. I had been taking them pretty regularly 5mg for about a year and a half and had been having some of the leg cramps. Still not entirely sure it's all related but it sure is weird everything stopped within 48 hours of stopping.
