I have been on Lexapro for 9 months. I started on 5mg, then 10mg, now back to 5mg again. It has been a lifesaver in a lot of ways. I was able to cope with my daily life and I have let go of years of anger/pain. My problem is now even with all the positive changes I am tired all the time. All I want to do is stay in bed and sleep. I have no get up and go and i'm a stone and a half heavier too. Can someone give me some advice.
