...and what's your blood pressure like? If you're taking any kind of medication that has a diuretic affect - there are many of them, even alcohol... that will increase the natural diuretic effect of low carbing. This causes low blood pressure and dizziness.

...and electrolytes? Are you taking the recommended suppliments of potassium/calcium/magnesium and/or getting enough from the food you're eating?

...and what about that ear infection? You probably have a more serious infection than that, if your white cell count was high.

Quit LCing if it would make you feel better, but I hope you and your doc figure out what's really going on here - it takes a lot more than diet to render someone "debilitated".
