Welcome to SR, Eppi. Congrats on 4 days clean.
Alcohol was my drug of choice. I have never dabbled in the heavy drug world much, even though I consider alcohol one of the heaviest drugs a person can get hooked on. Hope you don't mind being surrounded by a ton of ex-drunks here.
But addiction is addiction, right?
You'll find a ton of support on these boards. It's a special place with special people who have been through the war and are always willing to listen and offer sound advice. You should definitely check out the Class of July thread for all of us quitting this month (raises hand). We have a good group there and we support each other on a daily basis.
Welcome again!
