I started to smoke second day after the surgery, back in 2008.
I remember I met my doctor on hospital corridors and he told me to quit because now is the time. I laugh and I didn`t listen him.
Now I quit since 2 March this year and I gain some weight.
So you can smoke right away, I did it, is not healthy but if you are desperate, as I were, might help...
I really hope you can stay without cigs
