The deal I made with myself was to eat whatever for a year as long as I didn't smoke. Cost me (or rather, I gained) 15kg (~30 pounds), but I didn't smoke once, not even a puff. And now that I'm secure in my no-smoking life, I'm dropping the weight. I hate being fat, but even so, the 30 pounds were worth it.
Smoking is so bad for you, anything else you can do to avoid smoking is worth it (except maybe heroin or meth).
So my advice: use any help available. Use nicotine patchs (have them ready at your place), nicotine gum, electronic cigarette if you need it, regular gum, sweets, a cup of tea every time you want to smoke, read Allen Carr, ask help from your entourage, just wait up until the tobacco seller is closed for the night, so you delay and when it opens again, you don't want it anymore, go see a doc, go see an addiction specialist, a psychologist, read Allen Carr again, etc. Each of these alternate scenarios are still scenarios where you don't smoke, so they count as a win.
Oftentimes (before this time) I failed because I thought there was a right way to stop (e.g. cold turkey) and anything else was a failure, so I might as well start smoking again. That's the nicotine luring you.
Hang in there: you know it's shite, it costs you money, it destroys your body. You know you look like a twat while smoking, and you smell like one. You know it. Act accordingly. Anything else is bullshit argument to get you back to smoking.
