Patches really helped me through the early stages, then I went and got pregnant so had to go cold turkey...
I used to find my weakest point (apart from the pub) was getting petrol, I was so used to picking up 40 B&H at the same. I used to try and fix it so I'd always fill up at a 'Pay at Pump' station, that way I avoided all the sweets too.
I stopped going to the pub unless dh would be there too (not that he's scarey at all !) and pretty soon hated going at all as I couldn't stand coming home stinking of smoke.
A word of warning though, after the inital physical withdrawal symptoms stopped (which is quite a short period of time, around 7 days I think) my brain used to play tricks on me
'well you've lasted this long so you've proved you can do it, so just having one every so often will be fine'
NO IT WON'T, everytime I've thought that (I've 'given up' 4 times) I've been back on to 20+ a day in less than a week. I have to think of myself as a recovering ex-smoker not a non-smoker, even after 4 years of not smoking (I once went back to it after 6 years, how stupid am I ?)
Good luck to you all, you really can do it and it's sooo worth it in the end
