I'm with Lance - best thing I ever did was giving up about ten years ago. Well worth the pain and suffering of quitting
I do think that it is in our minds to quit - if we genuinely 'really want to quit'. In other words, if we really want to do it for all sorts of good reasons, then we probably don't need all those endless patches and tablets and things that are pushed these days. The willpower alone is enough.
The purchase of Nicobate etc as an aid to quitting is kind of a prior admission to yourself that you can't do it by the strength of your willpower alone. And clearly, if this is the mindset at the outset, then any small thing is likely to throw you off the quest to stop.
For those considering quitting, I'd suggest collecting a whole batch of great reasons to stop - and there are plenty of them ! - and then just pick a date asap and do it.
In actual fact, I thought afterwards that quitting was blown up out of all proportion. And although certainly some effort was required, it wasn't as hard as I've heard some make out.
Anyway, good luck to all potential quitters
Cheers,
