Congrats dawgg. Click the Wecome Center in "pink" at the top left of your screen. You will learn what the site is about, how to post roll, etc.
This site is a place full of guys that have gone through the same feelings your going through right now, and a shitload of them are still pressing on. I'm still somewhat new here, but my suggestion is that you trash every can, spit cup/bottle at home, work, vehicle, etc. Get it out, don't temp yourself with a half full can laying around. Stay as busy as you can these first three days, and take advantage of what sleep you can get.
The vets around here will give you better explanations on how to use this site..I just wanted to let you know that Im here, and I'm quit too, and this shit is hard, but it ain't gonna whip me.
