as been said before, cold turky is the only way, my sister did the patches and is an on off smoker still. when i paked up i made sure that the mony i saved got spent on toys that had functions. crochet needles started leather work made a french knitting dolly thing. in the end the thing that engaged me for the longest time was a Kumihimo disk that i made out of a bit of 5 mm leather, here is the pattern i used (cut the slots by pushing with a chisel not a knife)
http://www.craftster.org/forum/index.php?topic=269386.0 fits in the pocket and after a while becomes soft and you can make usefull cords for knives and to wrap around the throtes of the smug
but more than anything else dont hate yourself if you forget or slip and light up again just remember why you gave up, swallow hard and carry on. for me it was tax and the sanctiond bullying from work collegues and other staff i though sod that and used the hate and anger that came in waves to reinforce what i was trying to do.
when you get your breath back you could try hedging, its great and keeps you away from people and allows you to play with large bill hooks and axes
I also found that i had changed as well, not so much a people person (never realy did play well with others anyway) but realised that i would wonder off to have a fag to give myself space and a break from others, no fag = no excuse to have a break. best thing i found out is you dont need an excuse, just bugger off for 10 mins. I think most of the mood swings and snapping is that when you stop smoking you never have those odd 5 mins away from others so it all gets a bit critical mass.
you will already know and have made lists of the benefits but the main one will come when you remeber the terible feeling at 1830 on a sunday that you only have 3 fags in a packet and realise that you have not had that for a week or so.
sorry to ramble but anyway, just dont hate yourself and remember to have a break from things/people and of course.... buy toys!!!
