I quit smoking in November and used the nicitrol inhailor; It is by prescription only. The program seemed to work well for me because I determined how much or how long I needed to puff on the inhailor. The product did curb the cravings for about 3 hours. Also, if part of quiting is needing something to do with your hands, the inhailor works well for that too.
I had smoked for ten years and had tried several different methods of quiting with no lasting effect. My friend told me about the inhailor, and I asked my doctor for it. I must admit, I was surprised my insurance paid for it seeing as a month supply was over $100.00. With insurance, I paid $5.00.
