^I agree. Though you could have been a bit dehydrated, if blood tests look fine. That has no correlation to eating and after eight hours or more of sleeping most people are dehydrated anyways (anyone ever wake up with a headache after sleeping in?)
I wish mine was so simple.
A little too hot, not enough water, stand up too quickly, stand too long (15-20 minutes), etc and I'm at risk for a near faint. Get my heart going too fast and I will faint... I'm really anxious about next week, I can't afford to be sent to the ER if something happens.
At least if one is out in the street no one can force them to go because of liability...
