doubt it, but guess it depends on the doc. do u want a "green card" or do u just want to sleep? my buddy takes melatonin to sleep, does him good, but i dont know if that'll screw up your bodies creation of melatonin so wait for some real advice from a doc. in my area the medical is as much as the street so for me theres no point, legal issues maybe but u can still get in trouble with a card either way...
