I am currently on 3200 mg of Gabapentin taken at a dose of 800 mgs 4 times per day. I can't tolerate pain very well. Most with my pain level would probably tough it out. I do hate the mental fogginess of it though, but I despise pain even worse. I would say a good portion of the questions I ask my wife begin with "Where is my........?" I too have to search for the right word sometimes as well. I've made peace with it I suppose. I held out for a few years before I gave in. It does help though....
