I've been on 10mg of Lexapro for the last 2 yrs to help my social anxiety. I recently told my Dr. that my sex drive had really come down. He prescribed me 150 mg Wellburtin XL. I decreased my dosage of Lexapro to 5mg over a week and now I'm finshed with Lexapro. I have been taking the Wellbutrin now for 4 days, and have been really dizzy. Almost to the point where I don't want to operate a vehicle? I hate it ! Is this normal? How long does this last? Should I concider going back to Lexapro?
