Well, first.. stop buying them...

2nd..   stop bumming them off people (tell everyone you're quitting, and that they're NOT to give you smokes)

3rd... when the urge does hit... do ANYTHING else to take your mind off it... walk around the block... drink water... get a BJ... anything... the craving only lasts about a minute...

Probably the most important thing, if you really want to quit, is don't stop quitting... sure... yer likely gonna fall off the wagon from time to time (I know I do when I got a few pints in me.. actually that's the only time I smoke anymore) but don't get down on yourself for that... it took you YEARS to become the smoker you are... it's going to take just as long to learn how to be a non-smoker... (There's a BIG difference between a non-smoker and someone who has never smoked... a smoke-virgin if you will)

And well, yer gonna have to accept that if you are a smoking addict, then there are going to be withdrawal symptoms... suck it up, and get through it...

Best of luck to ya eh!
