Given the apparent size of this forum, there has to be a few smokers out there. Also given that the majority of smokers would like to quit, this might hit a few targets.
So, if any of you are contemplating this, I highly recommend Electronic Cigarettes (despite their name they are not actually cigarettes).
I was a smoker for about 20 years, 'gave up' a few times but always cracked.
I started using ecigs last September and haven't had a normal one since. No cravings, no cranky moods, I've not even kicked the dog. Also the cost is about 1/4 that of cancer sticks.
Believe the hype, but get a good one though, there is some crap out there that's best avoided.
I could recommend a brand but I think that's against the rules.
