Do you think I have Restless Leg Syndrome?

You may have. I have it and it runs in my family. It is not like a leg cramp it is more like fidgety feelings you just can't keep still. I have had it for years and it can come anytime and keep you awake for hours on end. Pillows don't help, walking around doesn't help. There is a new med out for restless leg syndrome. I haven't tried it, but it might be worth a shot. I have had a many asleepless night because of this. Get with a doctor or try over the counter medication first and see if that brings any relief. Good luck, because it can be exhausting.
