I tried Lyrica summer of 06 to Dec.06, It made me soo. tired and didn't take care of the pain. I tried Gabapentine this year from May until Sept. this didn't agree with me at all. My speech was slow as well as my train of thought. I was very forgetful and became depressed and had nightmares and began getting hives when my doseage went up from 400 to 600 mg and fluid buildup in my ankles and face. I didn't like the way gabapentine slowed my down(mind) at first I found it really helped with all the burning pain, but in the long run the side effects were not worth it.
