If you are serious, you can do what I did 20 years ago and have a simple painless laser treatment. Then it cost me around £2000.00 but it worked and I haven't had a fag or a ciggy since

. There are places all over the USA and its very effective 85% stop, but they do screen you very well if they think you are not serious or just looking for a magic spell they turn you away.
Here's a place in San Diego that has a great reputation and the costs now are down to $400 approximately. Good luck
