Slow slow slow down Jade. First of all, glad you're here. Sounds like the slavery caused by your addiction has finally caught up to you.
You'll be in the
March 2016 quit group. Head in there and post your name and day count.
The first reason I'm suggesting to slow down is you are likely to gain a few pounds after you quit before you lose them. The first few weeks, your appetite will feel ravenous because you aren't suppressing it with chew any more. If you don't use seeds, gum, candy, whatever, to suppress the oral fixation, the cravings could potentially be even more difficult to get control of.
The second reason, is you can only quit for one day at a time (ODAAT). You can't change yesterday and you can't quit tomorrow until tomorrow becomes today. Take it in manageable chunks.
Welcome to the brotherhood, open yourself up to the accountability and quit your ass off. If you can do that, you will be successful here.
