I need to quick smoking as well. My surgery date is 9/28. My surgeon said I needed to be nicotine free 3 weeks before pre surgical testing. My testing is on 8/31, so I need to quit on 8/10. Lots of people will have tips... get suckers or jolly ranchers, write in a journal, knit, anything that keeps you busy and your hands moving. Honestly though, in the past when I quit for significant periods of time I just quit cold turkey. It only sucks bad the first few days to a week. After that, it is all habit and not physical. Hopefully it's easier for you than you think. It's soooo worth it as well.
