My girlfriend tried those but continued to relapse.
I quit smoking about two years ago and won't be going back. My method was to use chewing tobacco to get my nicotine for a while then slowly cut back on the chewing. Chewing was easy to quit because it was a nasty hassle for me. Once I was down to about 1 dip per day I was like **** it and quit all together. I trained myself not to smoke by adjusting my behavior during key craving times like in the car or after a meal. The hardest one was getting drunk and not relapsing. I got drunk 3 times at home and didn't smoke then went to the bar and got shitty with smokers around me and made it.
TL;DR **** cigarettes
My gf quit finally thanks to those nasty ass commercials "I'm Tina and I used to be a smoker" tracheotomy infomercials.
Best of luck with quitting
