I'm having difficulty quitting smoking ive tried several ways. Another doctor on here suggested chantix. What is this and do you recommend it?

Smoking cessation. May take multiple unsuccessful attempts before quitting. On average about 4 serious attempts before quitting. Many modalities exist to help quit smoking including use of nicotine replacement, Welbutrin or Chantix. Each has its own advantages and adverse effects. See a PCP for help. No doubt with determination and perseverance you will win.
