I just started taking meds for my anxiety. It got to the point where I was afraid that an attack would happen at any moment.

First, the doc gave me Ativan. That helped take the edge off, but knocked me out, though after a few days I was getting used to working through the sleepiness. I had another appointment today and he decided to switch me to Lexapro. This drug seems to have made it impossible for me to concentrate. Does anyone have experience with it? Will that feeling of being completely unable to think wear off? I have a big paper coming up and I'm scared that I won't be able to get it done.

Any insight would be great. Thanks all!
