getting some zzz's

1:30 p.m. right after lunch break, having taken an antihistamine for my allergic rhinitis I was close to falling asleep. I kept taking notes only to find out later on that my handwriting was not legible at all. It's not even funny. I was pinching myself, trying hard not to fall asleep as my professor discussed sleep disorders. I kid you not. I almost couldn't tell whether I was dreaming about sleep apnea or my professor was lecturing on it.
