Hi Eddie,
I was given Melatonin while in rehab and continued taking it for awhile after I came home and was recouping. I never got any sort of a high/buzz from it and was told by the Addictionologist and Pharmacist that it was "safe enough for even very young children to take". I was also told to make sure I bought the "pharmacuetical grade" **?} kind...not sure why...{something about animal by-products maybe?}.
Hope this helps! Good luck with your study!
