Don't ever give up. I had so many of the same symptoms for the first month or 2 I was on Lexapro. The doc just upped my dosage, and still I complained. After about six weeks, she added welbutrin and things got better. I honestly can say I've never been so happy and I don't feel like it's med induced, they just help a bit. Granted, I removed my stressors and I don't wake up every morning feeling the need to go back to sleep just to avoid them, but I think with my current med regime, I could face them anyway. Don't give up, like Karen said, see your doctor armed with your list of side effects and go from there. I was very lucky that the addition of just one med helped, but trust me, once you find the right med combination you'll be glad you didn't just give up and go on as you were.
Best to yoy!
