... the AM as my doctor instructed but it takes me about 5 to 6 hours before I start to feel human again after taking it. I cannot function like this as I feel really drowsy and numb and just blank. I work full time and I have a husband and 3 children. I started taking the Lexapro at night two nights ago and I got crazy anxiety in the middle of the night and I was very restless. The next morning and throughout the entire day I feel drowsy not as bad as when I took it in the AM but enough to notice how sleepy I feel. I also get headaches all day long. Do these symptoms subside? should I speak to my doctor? is there anything I can possibly do differently to make the sleepiness go away?
