So sorry to hear your RLS is worse. As I had mentioned. Mirapex also gave me insomnia. It's ridiculous that we are given medicine that keeps up awake for a condition that keeps up awake!!
I don't think you had said, but do you also suffer or been checked for sleep apnea? I ask because since I'm back to wearing the cpap mask, my RLS is non-existant. You might ask your doctor about having a sleep study, if you haven't been tested.
I'll admit, having to wear the mask is not the greatest, but when sleep deprivation caught up with me, I was thankful for anything to help me get some sleep.
Good luck and keep us posted. I'll keep fingers crossed that blood test results come back fine. :)
