I am taking Lexapro because of my symptoms of PTSD (anxiety, staying up until 4-5 am, hypervigilence, and depression). I have been on it for a month, taking 10 mg every morning. Yes, I also feel like I can barely keep my eyes open through out the day. When I do get to bed, though, I am out! Maybe I should ask my psychiatrist if I should change the time I take it also? The main thing that I question is if it is working. Anyone out there that experienced noticeable changes? If so, what are they?

Anyone experienced weight gain at all?
