I'm not a doc, but that sounds like a large increase at once, my max was 300mg, then we gradually dosed down to 150mg. When I was still at 300mg and family matters were becoming small triggers, we tried getting up to 325mg., well just that 25mg increase seemed to make me feel agitated, so sticking at 300mg back then was best for me, but everyone is different. I hope you are alright since I read and replied this.

Sincerely,
DE
