My doctor wants me to try Lexapro. I have read a lot of mixed reviews. Took sertraline before only up to 50 mg. Thinking of retrying as it started stopping the anxiety attacks and side effects weren’t too overwhelming. The problem was insomnia. My doctor says he is only here to advise me. I am sensitive to meds and scared to start escitalopram. It seems so much more potent than sertraline?
