Tired

When you get too tired do you get light headed? For some reason that is a good sign that I have not had enough sleep. My youngest son is a lot like that also. I also find that I get migraines when I've been lacking in sleep. It just shows how important it is to get the needed rest we are intended to have. The funny thing is I slept all night and for at least 8 hours so I don't know what my problem is today.=)
