smoking cessation
"I have been a smoker for 35 years of 20-30 cigarettes a day. Never seriously tried to quit until my doctor warned me that cessation is an absolute must. I didn't believe I'd be able to do it since the cravings were tremendous, and were over-riding all rational thought. 

I Started taking Champix.

Within two weeks I noticed that cigarettes weren't as pleasurable as before, and started to ask myself it was actually worth the effort to go out and buy another pack - I realized then that the drug has effectively eradicated all PHYSICAL dependence, and that allowed me to focus  on the behavioral aspects of my addiction. I have not smoked a cigarette since 3 months ago. Still have occasional cravings, but quite weak and gone after a few seconds,"
