It's been three months for me, not too bad. here's what I did --
Got a box of patches ready.
Marlboro sends out great coupons for their ecig thing. Get a unit and some of the cartridges ready (10 cartridges and a unit came out to $20 for me, i still have some 3 mos later).
I also got 5 bags of sunflower seeds.
For the first week i had the patch on each day, during cravings i had seeds. my wife and i drink frequently at a bar near here, the ecigs were a massive help while we were there (we still use them, mainly at the bar and not always). if there's a big event or party where i'll be drinking heavily, i will wear half a patch (i don't cut them, i just peel off one of the backing pieces and stick half of it on me). Probably doesn't help you at this point, but we had planned the timing for after the stress of holidays and for during the winter (we're in the North East). We don't smoke inside and it's damn cold out a lot of the time. Sounds minor but it has definitely helped a lot.
in my opinion, for the extremely bad cravings (later in your quit, use patches first) and triggers (ie. drinking at the bar or driving) the ecig things have kept me most sane. i think it's funny that, when i used to smoke, i thought they were the most ridiculous things ever.
good luck!
