No idea what seems to wake me up at 4:20 each morning, and I always count myself lucky when I can fall back asleep for an hour (or two!)  Doesn't help that I was up late last night (going to blame that on Wanda's brownies that I had for a snack yesterday afternoon, along with a bunch of Alex's chips & salsa.)

Developed a slight headache last evening, and woke up with a more intense one, enough to make me nauseated and cause my eye to weep.  Waiting for Tylenol to kick in, and may not get as much accomplished today as I had planned...
