Hi Erin,
I quit
with chantix after smoking for 40 years and
I think it worked well because, in the end, I really wanted to quit even though I didn't know just how much I wanted it when I began taking it : )
You should research it though as it can be harmful to younger people. As for taking his prescription, the first week is a half dosage so you might really need to get your own. It is expensive, but depending on how much you are paying for your smokes, it will be worth it in no time.
