I am taking Lexapro 10mg at night and then klonoping 1mg at night. I still wake up in the middle of the night and then can't go back to sleep. I cant function like this. I desperately need sleep. My doctor wants to do a sleep study, i don't know how that is going to solve anything. Do you think I need a higher dose of the klonopin. I have been on lexapro and klonopin for 1 week now.
