get some patches they may help,some girls have smoked all the way through from posts seen and they were ok,but i think they worry that you may have a bad chest when you wake up from anasthetic if you smoke,and it does slow down the healing process,but the more you stress the more you will smoke,try and replace the cigs with excercise,do a few sit ups,lol,run up and down the stairs a few times,this will put lots of oxygen in your blood,and deep breaths too in through nose out through mouth,hahahaha,youll be so knackered you wont want to smoke,lol.and drink loads of water,xxxx
