Taking mertazapine for Anxiety and sleep problems my doctor increased my dosage from 15 mg too 30 mg . I now can't seem too get too sleep without taking two 7.5mg of zopiclone too knock me out .I'm groggy and weak now almost all day . and I don't really feel like I slept well. Not sure if I should ask the doctor too reduce it .I'm still having waves of anxiety but not as bad
