hi charly i smoked right up untill the day of my op(naughty i know) the stress of worrying about the op only made me want to smoke more, felt so rough after the op that i havnt had a cigarette since(3months), smoking can delay the healing process so was a really good reason for giving up. as for the pill i think it increases the risk of blood clots wich can be very dangerous in operations or something like that. whens your op?xxx
