Wellbutrin is an antidepressant, one that happens to hang out a bit in your nicotinic receptors. I almost accidentally quit the first time I took it (for depression) but I was like, hey, guess I can quit any time and pushed through, I was down to two cigs a day. However, (I TELL EVERYONE THIS) the "quit effect" grows weaker every time you take it, and so don't go thinking you can just relapse and try again.
Some docs were leaving their patients on it long term because if they stopped the cravings returned. I see no problem with this, as long as Wellbutrin agrees with you. For some people, insomnia, panic attacks, etc., can happen. It is an ACTIVATING anti depressant.
Chantix is SIMILAR in that it FOR SURE is designed to sit RIGHT IN your nicotinic receptors and people quit because they get ZERO satisfaction after a while, from a cigarette. That's the idea.
I have no idea how they got it to do that and what ELSE it does, but there are just a few too many reports of psychosis and death and whatnot for me to desire it. Also, every doctor I have seen and asked has responded, "No Anna, I never say this but please don't try Chantix, keep smoking you will live longer."
Keep in mind that doctors are slightly more likely to access the "Negative reports of drugs from doctors, as reported by patients." Doctors are legally required to report adverse effects, although patients are allowed to.
The FDA has been ignoring those reports for some time, because it is smoking, but some doctors who hand it out a bit too much like candy should SINCERELY access those reports and take a family psychiatric history from the patient prior to prescribing it.
They don't though
