I am on 175 mg sertraline+30 mg ritalin+20 mg inderal. I have panic attack when I want to take a nap specially after lunch. Right before I go to sleep an annoying thought attack me and I make whimper, trembling and shaking this stops me to sleep. Do I need to take another medication such as lamotrigine(lamictal) or to decrease the ritalin dosage? Can anybody help me? Thanks
