I am 60. Started on 10 mg of Lexapro on July 4th. Only 5 days. I feel emotionally numb. A bit of diarrhea and keep waking up and can’t get back to sleep. Will this stop? I’m not sure what to do. My doc says to stop until symptoms decease and then cut my pill in half. I don’t even want to do that if this will continue. Please help!
