Me!, I commend you.
After smoking for 11 years, I haven\'t had one in 6 months. And dude, I was ADDICT-TED! I also really enjoyed it, and if they discover a painless cure cancer I\'ll start again tomorrow! Pointless daydreaming aside...
The best advice I can give you, is change your routine. You are through the worst part of the physical addiction by now, so it\'s a matter of breaking habits. What really helped me is that I quit a week before I went on vacation, and the whole different atomsphere got me through the death trap that is days 5-15.
Also, I must confess, I use a crutch. I bought a box of cigars, I smoke about 2 a month. It really helps with the whole mental "holy fuck, you mean to tell me I can NEVER SMOKE AGAIN!?!?!?" It\'s relaxing, I look forward to them, and their stronger nature completely kills the urge for a while. They\'re cumbersome to carry, and awkward in most social situations so you\'re not likely to pick up a new addiction.
Lastly, if you lapse, don\'t give up! I tried and failed about 20 times before my recent success.
