I've had several bouts of drinking. I quit on my own each (!) Time...3 I think. Never did drugs not even weed. I was a pretty mellow drunk mostly. My mouth caused some...ok a lot of offense at times. I did things I'm now ashamed of. I wont do them ever again, I do wrestle with guilt at times. I try to put the past in the past most of the time.
Btw, I didn't realize you were old like me lol
