I used to rage HARD. Lots of drugs, but especially alcohol (due to it's sedative / numbing effects and extreme availability). A lot of sources suggest that booze is very bad for BP people because it can trigger mania OR depression and cause many types of medication to stop working properly.

When I used to drink I would get overly emotional (euphoric or depressed) and definitely feel overly confident in myself.

Coming up on 3 months of sobriety pretty soon though so I'm proud of that
