I am a alcoholic in recovery for the past 10 years. I've tried to quit smoking several different times. I was prescribed Wellbutrin and the patches. Wellbutrin made me aggressive with suicidal/homicidal thoughts. Needless to say, I stopped taking that. Just recently I started the Chantix starter pack. Was worried about the side affects, but I feel great. Even when I feel I'm going to be angry or stressed, my mind/thoughts seem to calm down. I was smoking almost 2 packs a day, now about a half a pack. I know that Chantix is for smoking cessation. But I am free of stress. This came up in a conversation at work. A friend suggested Lexapro. I am going to see my primary next month. Keep in mind I have never been diagnosed with anxiety. Any thoughts?
