I took Prozac and buspar seperately then togehter back in July. The prozac always caused teeth grinding, but the buspar caused this weird face twitching so I decided to just take the prozac. I stopped taking both in Oct. In December, I went back to the doc and he put me back on both of these. The buspar was causing twitches again, so I got off it and went back on just prozac. My face doesn't twitch now, but I still am very conscious of my face and mouth, and feel that it is very tense. Maybe this is just anxiety I'm having, because when I previously took prozac by itself, I never had this. By the way this particularly bothers me when speaking in front of others. Anyone else have this?
