Anyone else get dizzy when they don't eat for X hours?

This has happened to me my whole life. I was skinny as a kid and am probably average now. Because of what you described I have been tested for diabetes every couple years and it has always come back and negative. I just make sure to keep a bar or nuts in my purse in case I don't feel good. I am working on continually improving my diet, but if I start feeling dizzy or shakey fixing it before it gets worse becomes a top priority.
