If you aren't currently drinking a 5th of vodka a day, quitting cold turkey isn't going to kill you. Not even close. you may get some night sweats the 1st week, but that's nothing. if you are ready to quit, just quit. You don't need meetings, a hobby, get big, or Ellen & Oprah. You just need to be honest with yourself. It's only a liquid. Just look at it that way. It's a liquid. You are a grown man, no liquid will ever rule your life again. People will say it's not that easy, but it is. Just tell the liquid to fuck off.
You can do it. You just have to want to. When you get the urge to drink, just look in the mirror & say no. Fuck that liquid...
Do it.
