Starting early yesterday afternoon I started getting cramps in my right leg; my toes were trying to curl up, and the muscles on the front of my shin would knot up. It was very painful, and trying to walk it off didn’t help. I took a couple of potassium tablets, which didn’t help either. The only thing that helped was the heating pad, turned up to "roast." After a couple of hours my left leg started cramping too.
The cramps finally went away, and then in the evening I got hit with stomach cramps; my abdominal muscles knotted enough to feel them under the fat layer, not "gastric distress." I wandered around the house half doubled over for a while, decided to go to bed, and then started getting cramps in my right shoulder. Wonderful.
This morning everything seemed fine, other than some minor joint and muscle pain, basically everywhere.
Trying to figure out WTF happened, I realized that my carb count was way up yesterday. Yeah, I gave in to the siren call of ice cream again. [sigh] The leg cramps started a few hours after that. And then when they went away, I had some more that evening, when the abdominal and shoulder cramps started.
Not a big enough sample set for proof, but likely an indicator I need to stay away from the ice cream, and probably out to go back to carnivore.
