my doctor gave me neurontin a couple days ago for nerve pain steming from my back. i am having aweful side effects. i'm drowsy but can't sleep, i have problems with concentrating, blurred vision, headache, nausea, stomach pain, i am halucinating both visually and audibly, rapid heartbeat, spaced out, uncoordinated, my teeth feel like they are ringing, twitching, and just feeling like i am drunk!!! the worst part of this medicine is that it doesn't even do anything for my pain!!! i called the pharmacist and he told me to stop taking it. i am in a great deal of pain everyday, but i'd rather be in pain and feel normal, than feel in pain and feel aweful!!! i just hope that this isn't a permanent feeling!!!
