Not only is it dangerous to mix medication with
alcohol to begin with, but also drugs and
alcohol actually make things worse not better. For example, he may be able to drink away his problems today but really all he is doing is pushing out that problem to another day plus adding the possible liver damage into his future. Or a DUI or a fight in a bar that gets him arrested, etc. There is so much that can happen, and with bipolar you already have poor judgement, especially during mania.
