My friend, lets call him cj, has been diagnosed with bipolar for 5 years now. In those years he has overcome a cocaine problem. Recently he has turned 21 and has been drinking a lot. A few of these times he has become hostile and once or twice violent. I was wonderinf if alcohol is a trigger for manic/dpressive episodes.

Welcome to the board! YES it can cause all sorts of problems for people with BP and People without BP.
