I'm not sure whether I'm on the spectrum, but I'll share anyway. When I first started drinking, it was one of the first times I felt normal, and accepted in social situations. In fact, I felt downright popular. Getting shitfaced was an essential part of hanging out with friends. It was always a few people I liked from work, at someone's house, and things were very comfortable. Not only did I like the social aspects, but it also felt physically interesting. I remember getting this puffy feeling in my face that felt really cool, but that went away after a few months.
But the novelty wore off, and eventually, my behavior started getting inappropriate. I'm ashamed of this, because of how much it goes against my values, but I would often go on racist tirades, even with friends of that race (Jews and black people, in particular). I would never notice how hurtful that was until I got the texts the next morning. It's incredible I never got punched at a bar, but I did manage to get friends uninvited from a wedding for burning a Bible at a party for some reason.
So I no longer get drunk. I'll have a few drinks at work events to take the edge off, but I won't get drunk. Other than that, weed has become my drug of choice.
