I am at day 11 and not one puff since quiting.
I still have massive cravings but don't think about the act of smoking anymore.
Cravings are perfectly handleable with NRT.
I went for a full on lifestyle change, cut out fags, booze, I am dieting and excercising. So 11 off the cancer sticks and 5 ib lost in the last six days so pretty much on an even keel at the mo.
Good luck all
