Spent all last night with recurring leg cramps but never in the same part of the leg. Twice was the excruciating and mysterious inner thigh one, twice was side of calf, once was classic charley horse, and several times was ankle freeze. Always the left leg. Eventually turned around in bed and put feet against headboard, which seemed to stop the cramps long enough to let me sleep. Cause is supposed to be dehydration, so I've been drinking water all day. Hope it works, but walking bike home from work with a new shovel on the carrier probably didn't help.
