I was started on Lexapro approx 2mo ago and have had less energy ever since. The first couple weeks were OK but now I get up and have no energy. Is this common? I have also gained weight and am constantly hungry. I was thinking about stopping taking Lexapro but after reading all the withdrawal sx people have went through I am scared to death. Does everyone go through withdrawal? When do the withdrawl sx start? Does the weight come off after stopping?
