A. Bupropion hydrochloride, better known as Zyban or Wellbutrin, has a side effect for some people of a reduced appetite, which can be a nice benefit for people who want to quit smoking. Bupropion is a prescription drug though, and must be used under a doctor's direction.

Nicotine lozenges may also help curb appetite to some extent early on in a person's quit program. A year long study looking at the efficacy of nicotine lozenges was conducted in 2002. It followed approximately 1800 people who quit smoking using either nicotine lozenges or placebos. Indications were that those participants using 4-mg nicotine lozenges had 45 percent less weight gain 6 weeks after quitting than those using the placebo. At 12 weeks quit, weight gain was 21 percent less, and at 6 months, the difference in weight gain between the two groups wasn't enough to be of significance.(1)

Medications to Help You Quit Smoking:

• Nicotine Patch
• Nicotine Lozenges
• Nicotine Inhaler

Some of the above medications are available without a prescription, however, do check in with your doctor and discuss your options in order to choose a quit aid that's right for you.
