I have major back issues and neuropathy in feet and thighs will get numb from hip to knees if I stand in one place for too long. That's one reason I had to go on disability 3 years ago. I'm a hairstylist and standing is mandatory. I also have internal vibrations. I take 400mg of gabapentin once a day and haven't had vibrations for over a month. Maybe once at a level 1 or 2, very mild. I have no side affects from it so far. I took it years ago with my pain medication because of the tingling and burning but really couldn't tell any difference. When I started having the vibrations, my neurologist thought it stemmed from a central nervous system issue originating from the brain and prescribed Fycompa with little explanation of what kind of drug it was. I read up on it and decided not to take it because of the potential side affects. It was my pain management doctor that told me Fycompa was similar to gabapentin and Lyrica so I decided to take the gabapentin since I was familiar with it. Maybe the ones having problems with it could try taking it at night before bed. Maybe that will work. Good luck.
