Not sure if this helps... as I am not on meds.

I have to be sorta careful with drinking, because if I drink too much at times I get depressed afterwards. But other times are I am perfectly okay (hardly ever have hang overs), just bit tired. So maybe it depends on cycle or what other things you consume? (I don't mean drugs, but possibly food/caffeine, whatnot). With one friend we'd always take b-complex before drinking (he claimed it reduces hangovers. Heard it from other sources). I know that for me alcohol/valerian and some other herbs are bad combo. No problems whatsover moodwise with the demonized alcohol/energy drinks combo (not saying my heart and liver is loving it though).

so yeah.... that is all i have.
