Dizzyness?
If you go too long between meals (shakes) your blood sugar will drop and cause those quick flashes of dizziness and lightheadedness...I still have it happen if I go more than 3 hrs. without eating. I have to eat every 2-3 hrs. to keep it from happening. Make sure you're getting at least 64oz. water (fluids) every day. Sometimes our bodies react in crazy ways when we take away the sugar and caffeine...don't worry, eventually your body will "figure it out" and be ok with it. Yes, its fairly normal but if it gets worse call your doctor.
