My mom has that I think..I don't remember the name of it, but it makes her have low blood sugars. My brother is a diabetic too. I have a question, you said your blood was like 50 something, when normal is 90? That's weird, cause ours is like 4-6 is normal. So at first when you said it was 50 I was like Uh, what? lol :X

I however have felt like that before too, somewhat. It seemed to just go away though...
