About a month ago my Dr. upped my daily dose of gabapentin from 1,600 to 2,400. After about a week of taking the new dose I started getting brain zaps off and on every day. I do take an SNRI but nothing has change with that. The zaps will start happening five hours after taking a dose, and disappear within an hour of taking another dose. I also started amphetamine salts around the same time, and I'm on 0.5 mg. of klonopin daily but I've been cutting back to half lately. Could the increased gabapentin alone be causing the zaps? Or maybe it's klonopin withdrawal since I'm tapering down? I'm also thinking that my brain is going haywire from being on so many different meds?
