LauraKHi Kay,
If memory serves, I started on 25mg/day and went up to 75mg/day before the pain stopped. It was such a tremendous relief. I was in graduate school at the time, and there was no thinking happening when that pain kicked in!
This was many years ago, so I don’t know what the current recommendations are. I weighed 110-115 lbs at the time, in case dosing is done by weight.
I’ve also used Neurontin (for a damaged nerve just a couple of years ago). It made me feel drunk, and I couldn’t function when using it at a dose that helped the nerve pain.
