Matt, please join our quitters on the Daily Check-In, I used a forum to keep me accountable when I gave up chewing tobacco. And yes, it was much harder than staying sober. Read all the stickies too, lots of helpful info.
You'll be adding years to your life Matt, trust me this is soooo worth it. I can't believe how much better I feel and look now. It disgusts me to look back and think of what I was doing to my body.
Good luck to you in keeping up the quit. You can do it!
