A book I've read that I would recommend is - Drinking, Drug Use and Addiction in the Autism Community by Ann Palmer and Elizabeth Kunreuther
I too was an alcoholic for many years. Whilst I quit drink and cannabis at the same time, I've recently started smoking again. As for alcohol though - I wouldn't want to go back there. With weed, I've quit 3 times now, each one for over a year. But I always went back because I fundamentally enjoyed the experience.
Drinking though - I used that to fill a gap, during a period of smoking abstinence. The feelings from alcohol are very different, and the hangovers, which eventually led to regular migraines were too much for me. Behaviours when drunk, and memory loss from being blackout drunk etc. were all very risky behaviours which eventually led me to quit.
I can't really frame alcohol in any sort of positive light any more. I didn't start drinking until my late 20's. The first time I drank, I got alcohol poisoning, at the age of 17. I didn't touch the stuff again for a very long time. Even to this day, when I see drunk people - they annoy me. It reminds me of how obnoxious and erratic I used to be when I was drunk.
But, we all have a means to cope, or unwind, or fit in. That book is worth a read though - it's quite eye opening.
