Reply #12: It must depend on your body chemistry.

I used to be a chain smoker, and sometimes I would get up to almost 3 packs a day. I was very addicted and had tried numerous times to quite but ended up smoking again. A friend gave me her Zyban prescription (she had been bulimec and could not take it). I was going to go the full 14 days once I started the Zyban, but quit after 10 and have never picked up a cigarette since. That was almost 10 years ago. Something in the drug messed with the part of my brain that signalled pleasure from smoking. I hate when people say, "If it worked for me, it will work for anyone." That's so not true. In the end, it depends on the effect a drug has on the person taking it.
