Cut out the sugar (I can't cite the source, right now, but I know I read it somewhere) because it apparently goes hand-in-hand with the nicotine processing (something to do with your liver)
Lots of water is good advice, also. Put some lemon in the water. Exercise (cardio especially) will help flush, as well. My advice is get the wife (girlfriend, etc) to help with the cardio (hint, hint). She will benefit also, as you won't be sucking for air as quickly or as often.

Don't wash a coat (or shirt, etc) that you have worn while smoking. Give it a sniff 2 or 3 days after you haven't had a smoke and you will see how bad it stinks.
I, myself have not quit, yet, but my grandfather still lives with us and he smokes all day long, so my whole house stinks, and it's all but IMPOSSIBLE to quit while he is still around.
Smoke some ganja, it'll calm you down
