I have been on Lexapro 20 mg for about five years, following stroke. I am sorry to hear about the uncomfortable side effects you are experiencing, but if you can hang in there (and with your doctors OK), and get through the side effect period...which can be from one to three weeks or four weeks- you might find Lexapro as an effective medication. I know I do. But, we are all different, and when it comes to medications it can be a trial and error thing. I suggest to give it an honest chance, before going on to something else. Each new drug we try has an adjustment period which you just can't get around, but of course...if it is absolutely intolerable, speak to your doctor.
