I quit a long time ago. It was rough, and years before I quit having cravings at certain times...but...now I can't stand smoke. It may not be fair to talk about me though, I only smoked for about 5 years.
My mother smoked from age twenty one until she was in her 60's, two or more packs everyday. (at 21, her doctor told her to take up smoking to help her calm down
)One day, she decided this isn't for me, and quit.She had tried over the years but wasn't really ready. This time it was cold turkey. no drugs, no therapy. she tells me she can't stand to be around smoke now. (She's 72)
I think that's the key. You've gotta be ready.
You can do this. It's be hard, but it WILL get easier. You'll be so proud of yourself when it's done.
Hang in there!
