Odd reaction

Adding this to my regimen caused me to grind my teeth in my sleep, to the point of significant pain. Perhaps the L-tryptophan interacted with something else I'm taking, either prescription or OTC, but that's just a guess on my part. Unfortunately, it was a side-effect that caused me to stop taking it after just a week.

Frist time I have tried this product. I have trouble getting to sleep, and this seems to help...sometimes, not always.

Only tried a few times. Makes me constipated. I noticed there is iron in it. Will try another brand.

I thought it will help me with my depression but instead made me more agitated, and gave me bad heart palpitations. Even started slowly, half dosage for two days, then increased to 500mg for the next few days then increased to two at night after a week. Had to stop after 11 days as I felt that I was getting worse. And I even ordered an extra bottle thinking that it will work and i better have a good supply. FEEL SO DISAPPOINTED!

Well I really believed this to be what I needed for a good nights sleep- but it didn't work. I can't believe it!
