"i was prescribed gabapentin for horrible, 24/7 ms pain, 300 mg 3x a day at first. it did nothing for the pain, and i spent the entire month i was on it feeling like i was drunk or on a bad 60s type acid trip; i dizzy, staggering, confused, nauseated. my doctor said to give medications a fair chance to work and the side effects should only last a week or so. she increased the dose to 600mg 3x a day when i got no relief from the pain. after a month i couldn&#039;t stand the awful side effects any more and was still in pain so i just quit taking it."
