I am on 900 mg a night. No negative affects.

I have been taking 300mg Gabapentin for almost a year to treat Functional Movement Disorder and it has made a world of difference to my everyday life.

I have trigeminal neuralgia. I got up to 5200mg of gabapentin. It was the worst drug I’ve ever taken. It took a year to wean off. Even when I started for nerve pain the side effects were so intense but I was avoiding my last effort: neurosurgery. Not only did I not avoid it I had it 6 times. I’m thrilled for people it word for. It was the worst prescription I’ve ever been on.

If someone has taken a high amount of gabapentin, it is important to contact emergency services or a poison control center immediately. from Google

@iri5200 mg. What doctor would prescribe this huge dose. I take 300mg twice a day for nerve pain in my feet. I have been taking it for 3 years. Works great.

A pain specialist doctor at a prestigious University pain clinic. My dosing kept going up.p over to you. Because my pain would go away and I wouldn’t approve. I had had all kinds of procedures done to see if those procedures would help. Not one did. One procedure actually permanently damaged, my trigeminal nerve in my face, so the right side is now permanently numb on the outside (lake when you come home from the dentist) but totally on fire on the inside of my mouth and half of my tongue, my lips, half of my chin. Just half on my face where the nerve is. There was a 98% chance that the procedure would work and take my pain away. 😭 I fell into the 2% that not only didn’t work but permanently damaged my face another whole time I’m still taking gabapentin and my surgeon said we need to start weaning you off that drug. and that’s when he started whining me and about six months after that surgical procedure that didn’t work I had my first MVD and that did work for eight months. I was pain-free and it was glorious 🙂

@irishgirl2005 I'm not litigious. but this looks like a lawsuit. Lawyers like to settle for a much smaller amount. Find one that will take it to court and don't pay the lawyer more that 30%.
