Cold turkey and a friend/fiancee/partner who is also wanting to give up
Two and a half years ago my fiancee and I were both smokers.
We would get through a pack of 20 a day, sometimes more (those people who always answer less than 20 when asked how much they smoke - don't kid yourselves, I did for ages!).
I was 28, she was 29.
We both looked at two things, firstly the amount of money we were spending on cigarettes.
We were about to move in together into a rented flat and we couldn't help feeling that a vast chunk of that rent we could make by simily stopping smoking.
Secondly our health - those horrible coughs, the out of breath etc.
So we decided we would stop.
We decided one week that we would stop the following week.
At midnight on the Saturday we had our final cigarette and we then burnt what we had left of our current packs of 20 (about half a dozen each).
Because there were two of us neither of us wanted to cave in first and neither of us wanted to look like a failure to the other.
The first few days were horrible, the end of week one not exactly great.
However here we both are two and a half years later.
We did not lapse once (well I know for fact I didn't and I've got no reason not to believe my fiancee).
It didn't cost us anything in gum, patches etc (which can be as expensive as the cigarettes your trying to give up).
Good luck.
Oh - to see how worthwhile it all is.
Within 7-10 days your taste will be something like 10x better.
So eat your favourite meal about two weeks after you've stopped and enjoy an amazing new taste.
After a week spend a little bit of time (just a few minutes) around some smokers and realise just how much they smell and then realise that as long as you're a smoker you smelt just as bad!
