Ill agree with the others that say the patch is the way to go. Ive smoked off and on for 17 years now and every time i want to quit i just go buy a box of patches. Usaully wear for 2 weeks or so till i dont need em anymore. Currently on day 5 of no smokes this time myself, will see how long it lasts. Its easy with patches, for me at least. Best to "start" to stop when you have a couple days off work or whatnot so you can stay home.
Hardest part is when drinking or doing other stuff that goes well with cigs. So if you reaaaly want to quit id take a week off drinking too at first. Once you get the smell out of your clothes and car it gets a lot easier.
Longest ive ever quit was maybe 2 yrs, but then ill get drunk as shit one night and smoke a few, then go to just smoking when i drink , then ill wake up with half a pack and smoke etc etc and it just snowballs to pack a day again.
I seriously feel smoking cigarettes is the most moronic thing we can do to our bodies. Its not like we get a buzz off of it or anything. Just waste money and smell like shit. We stand outside in 20 below weather to smoke tar, wtf is wrong with us ? Lil nasty butts littered all over the place.
Good luck man - it can be done if you really want to, as cliche as that sounds
