My head hurts

This could be from a number of reasons. I do have a cold and a cough and each cough sends a little burst of pain up there. And oh, yes, there is that lack of sleep thing. Last night was SOOOOO irritating. I had a full and stressful day yesterday and was probably a little worked up from that. Not a good day to decided to try skipping the allergy (sleep) medicine I have been hooked on. I went to bed around 9.30, tossed and turned until about midnight, got up to tend to Dylan, went back to bed only to decided to try getting UP and doing the crossword downstairs a bit. Went back to bed around 12.30 and tossed and turned until Dylan needed me again around 1am (poor little guy is STILL sick, hello, over two weeks later now!). Fell asleep at some point only to have my "alarm" go off at 5am. Oh, D... Of course HE is making up for last nights' lack of sleep now, and here I am... Typing... Afraid to close my eyes for I know the second I do, he will wake up.
