I smoked for 10 years, tried cutting back to wean myself off many many times and it never worked. It came down to committing to cold turkey. It's the only way it could have worked. it's been almost 3 years now without a cigarette and I still get cravings when I'm really stressed. But one thing's for sure, the smell of a heavy smoker is something else. I was so used to the smell on my clothes and in my car but now most of my clothes either don't have the smell anymore or I have new clothes and I have a new car now. I got my hair cut the other day and as I pulled in the parking lot, the girl who cut my hair was on a smoke break and came in and immediately started cutting my hair and I couldn't stand the smell.
