So if you have made a major lifestyle change than you know what I did. You try something from your old lifestyle and it hurts. This was pizza from Little Caesars, I had one slice of cheese and a bread stick. And now I am paying for it with a major migraine, yuk, OUCH. I am so regretting that decision. And I am so glad I didn't eat more than that! Now to does myself with water and try to move it through my system a little quicker because I've got a test to study for!
