I'm not a nurse... but I just wanted to add my 2 cents... I get scratchy throats in the winter, right now I have one... but they just go away. I haven't been sick yet this year. I drink more water when my throat gets scratchy.
Dizzyiness... hmmmm did you eat enough today? i know with BF, reading a book now, that you have to eat more calories than when you are pregnant! Thats alot

And alot of water!!!
Hope you feel better soon!
