Just wanted to say that it's possible to quit even with a weak will.
I've been smoking for seven years, partly chain-smoking, and tried to quit about ... well, numerous times (so much I can't remember anymore
).
But the tries to give up became more frequent with the time and I finally stopped last year. But I need to add that I had to stay away from my friends for 2 weeks to finally manage because all of them are (still) smokers.
And now I can finally say that I'm not addicted anymore. Although I have been smoking one or two cigs while extremely gaming with my friends, I just don't have the urge to get cigarettes when I'm alone or not physically engaged.
And I'm veeery happy about that. I actually can't express how much better I feel.
