You can take alot of melationin without hurting yourself, but you have to build up to it, if you pop a buncha pills... you are going to have an... interesting night, also mixing with alchohol makes you have to pee alot during the night, not good for your kidneys but neither is drinking.. umm

I take 10mg and sometimes have had a few to drink.

But My body chemistry is weird, I am fairly resistant to most things, so my dosages are usualy higher than normal.
