I have had extreme anxiety that left me in a non-functioning state I have tried several pills and nothing helped until Lexapro! I have been on 10 mg of Lexapro since February 10th. I started taking it around 10am, this last week I started taking it at night. I feel awesome but I also feel like I could sleep 24 hrs a day! I've read where some people were over the fatigue in 4 weeks, has anyone had it longer? Should I cut it down to 5mg? Will this extreme fatigue ever war off? I am on Klonopin, but I have cut the dosage way down. Could someone please help. Also, please no negative feedback, I don't need that in my head.
