I think there is far too much confusion between everyone in this thread as to what pills OP is actually alluding to. Nobody has been wrong, but who's to know which pills actually correspond to OP's instance.
OP- for anyone to actually give you accurate information, you're gonna have to fill in this blank. Each and every different kind of pill is going to have different effects and different reactions with alcohol. Generally no pill is good to mix with alcohol, but beyond that, they're all gonna have different degrees of harm and a varying array of reactions....so we're gonna need to know what it is exactly you're talking about.
