Going to the doc is a good option, I used Champix to quit. I've been off them for years and will never go back. It blocks the receptors in your brain which cause the cravings so you constantly feel like you have just had a fag. If you try and light one up, even if it is the first of the day, it tastes like the third or fourth chain smoked fag, not appealing at all. You wean yourself off fags as the dose of Champix in your brain builds up, and stop on day 10. I didn't even make it to day 5 before I quit. I got absolutely no cravings at all. The most I felt was a slight twinge 2 months later when I started decreasing the Champix dose to zero, but by then the addiction was a bit of a toothless tiger. It was easy.
Possible side effects are depression, I think one in 10 people suffer. I noticed some mild down moods, but was able to keep them in context, as I knew they were being cause by the drug. The doc's advice (as I lived on my own) was to tell as many people as I could to keep an eye on me and to check in regularly with the doc. I also got some mad dreams.
Like I say, it's never going to be easier than if you temporarily alter the chemical makeup of your brain. I thought about those e-cigs but to be honest I don't know anyone who has successfully kicked the nicotine habit using those. Sure they don't smoke cigarettes anymore but they are still hooked on nicotine. And I don't know one single doctor who will stick their neck out and endorse them as safe. There are more and more grumblings coming out of the medical research industry that there just isn't enough known about these things so I would tend to be more cautious about them. As far as I know the industry is unregulated. They aren't classified as a drug, so any punter could set themselves up as a e-cig manufacturer and put the factory floor scrapings into them. I would much rather trust a rigorously tested pharmaceutical product which will have no nasty surprises...
