Hi
Frozen, congratulations on quitting smoking!! Awesome!!!
Yea, about the weight gain, everyone tells you to eat celery and carrot sticks

, yum like that's going to take the place of a cigarette. I gained about 15 lbs but in my case it's probably a combination of quitting and depression. I'm back to dieting again hoping to lose 25 lbs in the next few months.
Don't worry about the weight gain at first, that will settle down... I've read the average person gains 5-10 lbs when quitting smoking. You can do something about the weight after you quit. Just make sure you aren't snacking (alot), that you are drinking alot of water and you are getting some exercise.
Good luck and keep us up to date about the quit!!
