i think the to low of calories was the trick. i wrote down everything i had eaten for the past two days and it wasnt much. we were on the run so much i just got protein here and there. today i had 3 boiled eggs with avacado and mayo, then chicken breast with butter and 2 pickles, and now im feeling much better. could have been the salt too, as i had drank a ton of water for two days. thanks so much
