The mood swings are pretty bad
Hang in there...this is all happening to you because of some drug that's going to kill you! Go to this site
www.mWilden.com/QuitTime/ and grab yourself one of the counters for motivation. Get gum, hard candies, twizzlers etc. Anything you can put in your mouth to take your mind off the fact that it's still not getting any nicotine. Celery sticks, carrot sticks are good too...and better for you than candy. I've got a whole damn list of shit I chew on now
Good luck!
Remember, the worst part is the first week....day 3 or 4 are killers but after that it's a piece of cake!
