Help! It is almost 1:00 AM and I am so exhausted I know I could fall asleep instantly if only my arms and legs weren't so darn restless. I am falling asleep right now, but my arms won't let me stay asleep. Legs either. I haven't had this for so long that I wonder. Did anyone get this after taking a medication? I took a Flexeril for the first time in a super long time tonight. Could it be the medicine? Or just my FM?
