I have been taking gabapentin on a daily basis of 300 mg every 8 hrs 3x a days so 900 mg total. My question or questions would be, I do not feel anything from the gabapentin as in no dizziness, no sleepiness. Nothing from it question is why is that? Secondly I don?t know if it?s just in my head but since taking gabapentin I have been feeling horny & even my wife has noticed it. Why is that? I thought it would have the opposite affect. Thanks.
