I've been having allergy problems the last few days, which i think is transitioning into a cold: serious congestion and post-nasal stream. Before i went to bed last night, i got it into my head to take a 24-hour sudafed pill around dinnertime. It seemed to help, at least a little. I had a little bit of trouble getting to sleep, but dropped off around midnight.
I woke up to what I thought was my dog Mercy snarling in my face at the side of my bed, but this changed into my wife breathing behind me as my head cleared. And my, was my head clear! It was 1:00am, and i was wide awake. I guess the time-release pseudoephedrine kicked in to wake me from a sound sleep. Yikes. I have arisen and am now puttering around on the internet, hoping this side effect will wear off in time for me to get a nice early-morning nap.
UPDATE: At around 3:00am, i decided to call it a morning and go back to bed. Strange things during drowsy time: i had the urge to hum softly and monotonously while settling in, and as i drifted off, i would occasionally utter a completely random word at incidental intervals.
