Hi Eve, I have early lag cramp as my morning calls! I know one thing that will bring on the cramp is if my blanket is stretched too tight on my feet! I always loosen the top sheet and the blanket so they don't touch my feet! Also, I massage my legs and feet in bed before I fall asleep! Sometimes, I suffer from pinched nerve on top of my right foot, like an electric shock that kept me up all night. It usually lasted 24 hours, but during the day I can function without interruption! My primary doctor doesn't know the causes and didn't offer any remedies! I also drink powder Turmeric tea with a touch of black pepper.
