Even my blood is jumpy.

I awoke with a fairly nasty tension headache this morning. I fell back on a technique that is becoming increasingly common: take my morning dose of Excedrin and get back in bed, trusting in the caffeine to wake me up once it starts taking effect. It is a strange thing to be awakened by caffeine; the amount in my dose is equivalent to that in two cups of coffee, all in one shot. I lay in bed for a while, reflecting on the oddity of the sensation, as if I could feel the blood running through my veins. I am also curiously aware of my stomach, no doubt due to its emptiness when I took the meds. I'll have to put something else in it before too much longer, I suppose.
