I have heard nothing but BAD things about Chantix. The side effects are dangerous. For one, it mixes badly with alcohol, and medications. There have been many instances of somnambulism (sleepwalking) and driving while asleep. Oops. Erratic behaviour and nightmares are common complaints. In my town, a couple on Chantix said they had nightmares. One night they went out for drinks and came home, went to sleep. At some point the guy had a sudden personality shift and became violent with his girlfriend. She claims that it had never happened before, and she made him leave. He became angry and confused and somehow ended up pounding on a NIEGHBORS door in the middle of night, thinking it was his girlfriends' place. The neighbor is armed with a gun, and on the phone with 911. His wife crying, as an unknown man is screaming nonsense and trying to break the door down in a rage. He fires a warning shot- through the door, about 6 feet high. Well, the guy outside was pretty tall and he died instantly. It was a tragedy, he was a very talented musician, some say about to make it big. His girlfrlend claims he was never a violent type, and his friends and family all agree that it was the Chantix, mixed with alcohol, that caused his erratic behavior. They say he wouldn't react that way to a few drinks. Some people say that he must've thought he was dreaming, or in a nightmare and couldn't wake up. No charges were filed on the neighbor, as he was within the laws around here.
Anyway, I encourage anyone to quit smoking cigarettes for good. But read up on that Chantix stuff... I think that and some sleeping meds and antidepressants cause a lot more car wrecks and other accidents in America.
