The dizzy spell sounds like a classic IR result. Did you get the results back immediately with what happened to your blood sugar?
When I had my test, my endo told me to go and get a high protein breakfast -- eggs or steak or something that would balance out all the sugar they put into the solution. But they should have waited a couple of hours and taken blood samples during the test. By the 2 hour mark, you should have come down from the sugar high they sent you on. Or did you leave immediately?!
I'm sorry you're feeling so sick and I really hope the doctors are able to get you on a plan that works. I always advocate being your own champion when it comes to your health because your doctors may not know everything that's going on inside your head/body. Communicate as best as you can and trust your gut instincts.
