Welcome! Hey, day three really sucks but tomorrow will be ALOT better. You just have to hang in there and refuse to fail. Find some sunflower seeds, life savers, altoids, gum, fake snuff, what ever it takes to keep the shit out of your mouth. I'm just a few days ahead of you and just started my journey.
Stay close to this site, it helps. Read, post, read some more. Lots of good stuff here.
IT DOES GET BETTER!!!!! HANG IN THERE!!!
