I'm on 1250mg Lithium, 60mg Mianserin and recently upped Risperidone 2mg. I stay extremely thirsty but also have excess saliva so it feels like I'm drooling! I can't stay awake after 9h30 at night. Take all meds at 8 in the evening except 500 mg Lithium in the morning. Kinda feel like a zombie. Is it normal?
