That's some serious help you have being offerred above ^^^^^. Follow what those guys say, they've all gotten many other quitters through the hardest parts!
Each hard time is one more time you WON'T have to get through again. Just beat this bitch back one challenge at a time. One victory = one in your column, one situation you are teaching this evil addiciton that you aren't going to fall for any more. There are all sorts of tricks it throws your way, but you CAN do it. Many here, and elsewhere, have. Just follow the program as closely as possible-- it works. Post every day. Get to know some friends from here- newer and older quitters both. Record your journey here to remind you what you've been through. Reach out for help if you need it. It's all up to you now, everything else is here for you. Can you be as tough as the 30, 40, and 50 year old men around here? I think so- I've seen a few in their early 20's make it so far, and I think you can.
