I'm in the process of quitting. Nothing ever good comes from drinking and a hangover ruins all plans for the next day. Pot costs so much these days that it almost robbery, the money I've spend on it could've bought me some really cool shit. Tobacco is definitely the least enjoyable of the three and a pack costs 7 bucks with taxes, and the only time I ever crave one is after I had just put down a 2 lb burrito.
The feeling I get from these things just aren't worth it anymore, especially with a busier schedule and working my ass off for the little money I do make at the ski hill and sub shop.
