I've had more morning lows than I care to count.
When I have a low in the middle of the night it usually wakes me up. I don't know what it is that wakes me but I'm so grateful that my body recognizes the low enough to rouse consciousness and alert me to the situation. I stumble around in the dark and get some glucose in then usually just crash back into bed.
When I wake up with a low I immediately have a headache. Sometimes I get this strange feeling that a low is pulling me deeper into sleep. That kind of scares me. If I don't wake up... how low will my blood sugar drop? Sometimes I get migraine like symptoms with a low. Bright spots in my vision, bright spots when I close my eyes in the shower. That makes the headache start to pound.
Morning lows put me in a bad mood. After having kids, I've become less of a morning person anyway. Add a low to the morning routine and I'm basically an angry bear in the morning. Sigh.
Lows always suck. But lows in the morning... those are the worst!
