This sort of thing happens every once in a while. Some of these events are just allergies but the worst of them are head colds, and I have one. Right now I have one. A head cold. My normally large nose feels truly gargantuan tonight. It's the middle of the night and my decongestants aren't working well enough to let me sleep.
A "big doze" is no fun, it just makes your head feel off-balance. I have to concentrate like the blonde looking intently at the frozen orange juice carton, I have to really concentrate, to figure out how many hours to allow between doses of decongestant and again to remember when I took the last dose. Eh, let's see. Nine-thirty to one-thirty; four hours - I am good to go with another dose...ok, so allowing half an hour for the stuff to start working...ehhh....maybe I can go back to bed at two.
