I know everyone is different but for me a was on gabapentine 1600 mg daily not sure if it was doing anything so after 1 1/2 yrs I weened off it, went back on after 1 1/2 months and tried it for another 3 months. FOR ME I FOUND NO DIFFERENCE, I am done with it, if it was not working why be on it. The search continues. Just remember everyone is different
