I’ve been addicted to drugs, twice. Used to get 200 blue Valiums a month, and I’m still on the oxycodone, 30 mags., going on, since 2016 I think. Oh yea, back in late 90’s I used to get between 100 to 150 oxycotins, the big ones, 80 mgs a month, the absolute worst were the oxycotins, worst withdrawals ever, thought I was gonna die. Lasted 4 or 5 days of pure hell, didn’t think about consequences. One day my buddy said his doctor was just gone, left his wife, moved out of state, never heard from since

My bud (who I quit with) and I used to pick up 100 blue Vals a week each. Luckily, that was for less than a year.
Already a whiskey drinker. 2-3 blackouts a week. That's when I "hit bottom" and had to quit.

I don't want to be cavalier about my alcoholism. It was one of the hardest things I've done to quit.
I do know about the toll it takes on your body. I was starting to have stomachaches all the time from drinking, so I just started with beer to "coat my stomach".
My best friend and partner in quitting had been a passenger in a wreck which nearly killed him. Took out part of his liver, docs made a new gall bladder. So, he concentrated on the Vals and other downers since the alcohol was even more of a poison to him. Just drank a little less.
You keep on drinking in the face of clearly seeing the physical damage.
I have been drinking occasionally now that I'm an old fuck. However, it was 40 years ago that I quit. I have a rule to not drink more than once weekly.
I could
not have done it occasionally those 40 years.
I think that a big factor in where I am is that I became a pothead when I quit booze.
Pot is a hard habit to develop, but it's worth the effort.

Lottsa people on here had drug problems and only smoke pot now. It's still bad, but your life doesn't go down the tubes. It's sustainable.
I quit pot almost 20 years ago. I had a daughter to raise and work to do.
Been smoking some in the last year or so (retired, my work here is done).
I see that as way more of a thing which will become a habit again. Not particularly worried about that.
It took me a year or so until I could be in situations where there was drinking.
I used to love going to jazz clubs, so being able to go to a bar and listen to music and not drink was a biggy for me.
One day at a time. Don't say you won't ever drink again, that's too hard. Say, "I won't drink today."
