Can lexapro cause add symptoms? I feel like this is happening to me... Also. I have been on it 7 months and have gained 13 pounds. have a hard time getting out of bed or getting anything done .. Libido is gone. Just kind of frustrated being on this drug. It has def helped with anxiety . just kind of feel down about my weight gain and the fact I just can't get anything done or be motivated . I'm also so spacey . will be letting my dr know my concerns soon..
