Hi,This is my first post also. I have exactly the same problems, except I get woken up about an hour after I fall asleep. I get the same building up feeling followed by a body jerk then the build up feeling starts again an so on.. The only medication I have found to work is Tramadol, I've tried many things and have had brain and mri scans. My problems started following spinal surgery five years ago, up to that point I only had RLS. I take a low dose of tramadol every night two hours before sleep and this completely stops the jerks. Hope this helps.
