smoking cessation
"This is my 3rd time taking Chantix. The 1st time I took it for 3 months  and quit smoking for 3.5yrs. I experienced the dreams but no other side effects. The 2nd time I took it for 1 month & quit smoking for 6 months. I still had the dreams but had nausea also. This time I've been on it for 4 wks, smoke free for 3wks. I'm having the dreams and had nausea for only the 2&3wk, but in the 2wk I started experiencing more side effects. I started feeling tired lazy bummed and in a bit of a depressive state. In the 3wk I became paranoid and obsessive with racing thoughts. Its hard to focus and now in the 4th wk I question if I'm hallucinating or dreaming. No thoughts of suicide. I quit taking it today & hope to stay smoke free."
