Ann, maybe it's the stuff that Rita takes.
Yesterday I spent the morning cooking a huge pot of beef paprikosh, then cleaning up the mess I made in the kitchen.
Serge went shopping for the groceries so I had to put all of that away when he got home, so I got lots of exercise.
Today I did 30 minutes on the treadmill and glider, calf stretches. My legs were pretty good again last night, woke up at 2:30 and the right leg had twinges in it, got up, had to go to the bathroom anyway, took 2 of the leg cramp pills went back to bed and since then I have been fine.
