Did you only eat from 9am to 1pm? Thats only 4 hours. Thats more like one meal per day. Anyway, i can see how your electrolytes could have gotten out of whack. That sounds to me like a reasonable explanation. When my "water level" is off, i am out of sorts in every way imaginable - physical, mental, emotional. But when im "flushed", im like a kid again. For a short while. Its like Cocoon.
