Quitting smoking.
Congrats Jack you'll do fine the secret is to keep your mind/hands busy so you don't think about smoking [thats how i do it] it will get easier as time passes but the cravings have not gone away for me yet [1 year in november] they may in time but sometimes they are stronger than others, my worst cravings are at car cruise ins when i'm sitting idle i have to get up and walk around till it passes,but i can hang out with smokers at work after lunch and don't bother me at all. Hang in there you doing great!!!
