What's the obsession with drinking today? Second thread on the topic in a couple of hours.
From the time I moved out of my parent's house and began sharing a bed with another person, I've had to be drunk to get to sleep. I use alcohol to self-medicate, because I refuse to take Big Pharma's Laundry List Side Effect toxins. I've known friends who have been awakened by cops while sleeping in the middle of a busy street at 4:30 in the AM, and who have gotten up in the morning to find their kitchen in a shambles and bizarre concoctions in the fridge because they were sleep-cooking. No thanks, I'll stick with my beer. It doesn't relieve my anxiety much, but it does distract me from it momentarily.
Weed always relieved my anxieties, but my state hasn't made MM legal yet.
OTOH, I haven't used alcohol for socializing since my early 30s, but that's mainly because I just don't socialize anymore.
Of the people I've known over the years who were (or whom I strongly suspect to be) on the spectrum, its about a 50/50 split between drinkers and non drinkers. I don't think there's any association either way.
