Zinco- the klonopin bottle says twice a day as needed . I need to take my lexapro in the am and trazadone at night. I know however the Lexapro was staying the same. That much I remember. But she wanted me to start with half a tablet first...but I don't know which one, klonopin or trazadone. She also said to take either the klonopin or the trazadone 1 hour before taking the other. Do you have experience or advice for this?
