Welcome @tdscott, I can't begin to imagine how hard it is to deal with the extreme pain you must feel at night when it flares up. You mentioned it started with a bad car accident in Jan 2020. Do they think your pain is due to injured or compressed nerves caused by trauma from the accident?

I take 1450 mg of Gabapentin(Neurontin) everyday for a few years now for nerve pain. If I forget to take it within the time prescribed I get nervous feelings. I call them the Hibby Jibby's. I ran out one time and could not get my refill until the next day. 10 hours after not having one I was in excruciating pain. They say the only thing that compares to nerve pain is child birth. I just know that I have a high tolerance of pain but only two types of pain have ever made me cry and that is nerve pain and severe migraine pain. The extended release does not work as well as the regular Gabapentin and starts losing its affect about 4 hours in instead of the 8 hours it is suppose to.
