I'm up to 450mg a night, didn't even take the Gabapentin the past couple days, I just don't think they're doing anything anymore. My guess at this point is the Gaba just kind of puttered out. I still haven't taken the Oxcarbazepine yet during the day, my nerves get worse in the evening, but also because of the cold. So if I keep my feet warm it seems to help more than taking that stupid Gaba pill in the morning.
