First day on meds. Well, lexapro knocked me out and I slept through all of my alarms (I am a notoriously heavy sleeper), and I was late to work. The entire day I was out of it and had a difficult time concentrating. I feel like I have brain zaps or something. I'm on the lowest dose too. Well time for another dose. I hope this will stop. I'm going to call my doctor tomorrow. Sorry for the weird post everyone.
