"i have a herniated disc at c6 and a pinched nerve that shoots pain down my left arm. i started taking neurontin 300 mg once a day for a week, then two a day the 2nd week, and now 3 a day. i&#039;m a local truck driver, so reading your reviews had me worried. when i started this medicine, my doc also started me on robaxin. everything was okay until the 2nd week. i got the high feeling for about that whole day. then the third week, same thing. i stopped taking the robaxin cause it leaves me groggy and unfocused. i have almost no pain in my arm after 3 weeks on neurontin, even after i stopped taking the robaxin. this medicine is awesome. i had doubts about its effectiveness until reading your comments. thank you everyone. it doesn&#039;t affect my driving ability after i stopped the robaxin."
