Managed to give up that little habit a few years back.....
Never really liked it much......would go out, get drunk and automatically look for ciggies....then I would wake up in the morning, have a few fags left (brit slang BTW so dont bother!!!).......light them up and soon I was smoking all the time.......after a few years I decided that if I didnt give it the kick, then it would be harder later on.
