What can I expect My doctor prescribed me Lexapro months ago after having a terrible fire followed by a terrible car accident which sent me into a whirlwind of PTSD anxiety manic depression and just five days ago I started taking 10 mg tablets at night because they make me drowsy in the day . Today I decided to try taking 5 mg at night and 5 mg tomorrow morning has anybody found this to be more helpful and not feel as groggy? How long before I start to feel better againlooking back now I realize that I have been walking around untreated for a very long time and struggling with my Zaidi's on my own now I've decided that I can no longer do this and I need the medication in order to function I'm too afraid to drive I'm afraid to leave my house I'm afraid of everything
