I've never done that kind of drugs --- I was addicted to Xanax, but my MAIN problem was booze. I'm a recovering Alcoholic/addict.
When I first got sober, I remember watching the movie "Days of Wine and Roses" which is a very sad, tragic, and also hopeful movie! It's about a couple of alcoholics, where the husband recovers, but the wife doesn't. It was difficult for me to watch, since I was newly sober! And my HUSBAND didn't recover, but I did.
In years past, I've had MANY drunk dreams, where I'd wake up and I thought it really happened! I'd be sweating, crying, etc.! But actually I was grateful for those dreams because it kept me mindful of where I'd been, and how I NEVER wanted to go back there again -- it was totally miserable.
In a month, I'll have 20 years sober so seeing those movies, or watching someone drink or even smelling booze doesn't bother me anymore -- BUT I'll never take it for granted. I cannot assume that I'll NEVER drink again, because I don't know that. I've seen people with more sober time than me go back out for "further investigation."
So yes, in my earlier years, it DID bother me in movies, but not now. I wish you the very best, my friend. God bless and please take care. Hugs, Lee
