I did hypnosis. Not sure if I was actually hypnotised but I think just the positive reinforcement of someone telling you for a couple of hours what a great decision you're making was enough to get me off my 20-year, 20-a-day habit. And it was a breeze. Rather than feeling like I was in a prison with my ciggies just out of reach, it felt like I was on holiday. Brilliant.
Don't believe all the shit about how you need drugs and gum and the terrors of withdrawal and all that. The nicotine is gone in about 48 hours, the rest is social conditioning. The thing to remember is there are a lot of people out to make a lot of money by telling everyone how terribly difficult it is to give up smoking, who have a huge stake in making it actually as hard as possible.
I spent some time in a cancer ward this year. There was a lot of people with different types of cancer and I would say the lung cancer patients were one of worst in terms dealing with the treatments. Their body is already dealing with so much crap it can't respond to the chemo well and they spend the days suffering. Pretty sad that they mostly brought it on themselves.
Even sadder that outside the windows of the oncology section there were smokers lighting up every single day.
