If you don't exercise you realy might give it a try it helped me.

I stutter and have a weight problem. it hapens that if I am thin
and on a simi low carb diet i don't stutter nearly as much. Well
back in 1980 after losing ~40 lbs and maintaining that weight for
6 months. At this time I started using a method to controle my
stuttering which because of my weight loss wasn't as bad as it had been. The method worked extremley well for me and I no longer stuttered. Well life shows up and I started back smoking
again only to find if I smoked that method to controle my stuttering just wouldn't work for me at all. I would quit smoking
for a week and stop stuttering only to pick the cigerets up again. Over the next 20 years I would try to quit and maby guit for a month or so and gain weight. Well some times I just
just told myself i can eat anything i want just don't smoke.
Well 150 lbs later I was still smoking. Then I tried again using the
patch and zyban and although they helped I just couldn't quit.
Then I continued to use the patch and zyban and added taking a daily walk. Gave up the patch about a month later and quit
taking the zyban but continued to exercise. Three years later I
was still smoke free and had walked off 40 lbs. I stoped my daily
exercise and my weight loss stopped. But I am still smoke free
13 years and feel I owe the daily exercise a lot of the credit.
