Thank you all. Well I figured out what happened. It's the zanaflex! Might have been the Ampyra too but I came off both and have been fine. Tried zanaflex before bed last night and had burning legs again. No more of that for me.

The quest for a drug to help with my ridiculously spastic legs continues. The only good night sleep I've had in ages was the one night I took 1/2 a tablet of Ativan. Going to call my dr today and talk to her about that.
