brain zaps I use to get them but not on lexapro.I took it for a couple of months not sure what it did didnt give it alot of time .Whats hard about meds. is we all want to feel them working and in most cases if you feel them working right a way they knock you out . It takes time for the right meds. to work its very slow so most times you dont see or feel the changes till you look back at your self months to a year later .I heard great things about lexapro but the only way you are going to know if its right for you is to give a try and enough time to work.
