Your right, Gabapentin does affect the brain as do all Anticonvulsants. I know, i’ve been taking them for 55 years. Most however don’t bother me at all. It's to bad you had a bad experience with this drug that is very beneficial to many.
I took the max dose of 3,600 mg for seizures and Neuropathy and I didn't have any side effects. Unfortunately it didn't help either problem. My brother is on the max does for Neuropathy and other pain from a severe auto accident that helps him tremendously. I know a number of people who take this as monotherapy for Focal seizures with great results.
There are some drugs that I refuse to take but I know they give others relief so I can't condemn them based only on my experience.
I hope you find something to ease you pain without any side effects. Take care,
Jake
