Hey there again, would seem I was wrong but I noticed this:

"I got this EXACT same way when I was pregnant, so it has to be caused by something"

Do you know about gestational diabates? I really don't know enough about this, but it is a type of diabates different from Type I or Type II that many (I was quite suprised by the percentage but I can't remember) women get while they are pregnant. Given dizziness is a sign of diabates, and that you feel exactly the same now as you did when you were at high risk for it, I would suspect blood sugar.

Sadly though, I don't know enough about this... Just an idea.
