Well, I think I got my answers.. my surgery is Sept. 28th, so Ill definitely have to quit smoking by the first of September. They told us 6 weeks prior is efficient enough, but then I was told by the nurse that she seen patients not stop smoking b4 or after surgery. I need to quit anyway, I've been smoking for over a decade & it's time to seize the nicotine! I deifnitely think I'll try E-cigs! =) Thank you guys for your feedback!!
