Dizzy Spells

At the beginning of my pregnancy I noticed that I would get really dizzy on the weekends. I would be perfectly fine during the week, but on Saturday and Sunday I would feel like I would be about to faint! I finally realized that it was my blood sugar. I was getting up around 11:00 and would eat a bowl of cereal first thing, not smart! Once I realized what was causing it I stopped. Well now I am at the beginning of my 30 week mark and the dizzy spells are starting up again not matter what I do. Like clockwork no matter what I eat, every morning I get dizzy and have to drink a lot of water and just sit still. I feel really flushed and warm all over. I have never fainted before, but I am sure this is what you feel like before you hit the floor.
