I have been on Lexapro 10mg for about two months. It's working great, but it's making me so exhausted. I think it's the Lexapro that's making me tired anyway, it seems like the most logical explanation. I'm getting enough sleep, I eat well and I exercise regularly. I take it at night because I heard that this helps with the fatigue. It doesn't seem to be doing anything for me. Does anyone have any suggestions?
