We've all be there. Dude, it works. No lie, the shit works. Do you really want to quit? If you do, stay the course, get your head straight by telling that nicotine fucking demon in your head that you win today, keep your promise, drink water, exercise, do anything but chew, then in the morning wake up and repeat. The first few days DO suck and you won't have anyone here telling you otherwise. In fact, I'll be straight up honest with you, my first 30 days or so kinda sucked cause I couldn't sleep for shit and couldn't concentrate at work. However, since then, it's been great! I posted Day 265 this morning and can't remember the last time I had a real "crave" for a chew.
Stick with it man - like Leahy said, go balls deep!!
