I've recently been given the go ahead by my doctor to take 60mg. in the morning and my usual 160mg/night. Due to severe stress I'm going thru right now. I know 160mg. is the therapeutic dose, I was just wondering if anyone else has had to go higher like me? I'm bipolar 1 and also take clonopin, prozac and lamictal. I don't experience any of the major side effects from the drug anymore and feel comfortable taking it at this level.
