Pain
"I have secondary progressive ms and was prescribed 300mg 3 X per day for severe burning sensation. The first week was fantastic no discomfort which really helped with my ability to walk and energy levels. Then gradually over a period of 2 weeks the pain returned. I was then upped to 1200mg per day with no improvement.  Then upped gradually over a period of a year to 3600mg per day with absolutely no improvement of pain. 3 months ago I decided I was not going to take this drug any more as it was useless. After much reading I decided the best course was to taper off 300mg every week until I was on nothing.  I am now down to 600 mg per day and over the next two weeks plan to totally stop.  I have had no major side effects and still have pain."
