I am now on 2100 mg of Gabapentin & was afraid it wasn't doing much, until 2 days ago. I accidentally forgot to take my afternoon dose & the following 12 hours were pure, painful hell. My paid doc would like me off of it, but even he warned me to do it gradually. Nothing he has done has helped me & insurance only pays for office visits. I may try the "Summus Medical Laser" treatment he now offers at $160 per (you need multiple treatments). Out of pocket, of course. Anyway, the Gabapentin doesn't cause any side effects for me & I'm a small 72 year old woman. Since the worst pain occurs in the evening & night, I just increased my afternoon dose by 300mg & my PCP supports this. I guess I would rather take Gabapentin than opioids.
