smoking cessation
"Before the first week was up and before I even increased my dosage, I went from smoking almost 2 packs a day to less than 5.  When I tried to avoid smoking altogether right away, I had very bad headaches and a little achy.  I think it does help to taper down some so your body can adjust to the change of nicotine levels.  I have tried many times and many methods to quit smoking.  Zyban is by far the best."
