agh! cramp!...

Woke up this morning with cramp in my calf muscle. ouch! 'flipping hurt. Then to make me feel better cath shouted at me for waking her up! can't win! i didn't want to have cramp...
p.s. is anyone else noticing how stuffy it is at night at the moment? last night i was considering sleeping outside on the hammock under the stars.
