Switched to Lyrica from Gabapetin in April 2007 for burning feet. Have been varying dosage between 150mg to 600mg depending on pain. The lyrica pretty much does away with the burning. Nothing seems to help the numbness and odd feeling when walking. I have no side effects to speak of. I do alot of bicycle riding so my weight has not changed.
Recently started having burning in the back of my legs and buttocks when sitting. Lyrica does help but not as much as the burning feet.
Basically I would be burning up without Lyrica. I am grateful to have it.

Good Luck.
