That sux bro - god damn muscle cramps!
I've waken up a few times in the middle of the night and stretched my legs and bam pure leg cramp - writhing on the floor in pain for like 10 mins...
I remember playing tennis years ago with my shirt off acting all cool and shit to impress these chicks hangin out nearby and when I served the ball and streched up to reach it my calve got stuck and I was rolling on the court screaming like a biotch, then when I got up I had dirt and shit all stuck to my upper body cuz I was sweaty and had no shirt on - classic.
I have never had dual calf cramps tho *ouch*
I did however get dual quad cramps skiing down Mt. Tremblant for the first time tho.... legs were not ready for so much turning... maybe if there was an avalanche too at the same time it would have been the same as your experience.
Rock on
Nothing a bottle of Cristal can't fix
