Fellows on the forum actually helped me get off them so you're in the right place mate!
I'd tried a handful or more times to quit, came on here and got offered heaps of advice. Jason even extended a hand from down south by letting me text him when I was craving a smoke and sent me back helpful advice.
Just stick at it, the first week it's like being in the twilight zone and sucks a fat one however it wasn't nearly as bad as I thought it was going to be. Biggest problem I had was the niggling little thoughts of "ahhh it's been 3 days, you'll be right to just have one...." and 3 later I'd feel guilty about starting the count all over again!
You're your own worst enemy sometimes, just make sure you're smarter than yourself and outsmart the smarts of your nicotine self!
