It depends on the person. I do agree alcohol and benzos probably do it for most but personally alcohol and benzos do nothing to me. I'm the same only drunk if that makes sense. People on stimulants seem pretty scary too.
Opiates tend to make me into a raging cunt, I have to catch myself and watch my reactions very carefully. It may because it's the only time where I actually feel comfortable being me and all the aggression I keep down on a daily basis is coming out. Or it could just be hormonal or just the effect opiate has on my system. I know I'm not the only one this happens too I've seen lots of threads on "opiate rage"
oh yes. It exist. I get cranky sometimes when i know i have to hold off of dosage to make me last all month. I was never this way.
