QUESTION

I can't remember if I took cold medicine ten minutes ago or if I just THOUGHT about taking cold medicine ten minutes ago (you might think this absentmindedness is a result of the cold medicine but you'd be wrong) so now I am stuck with quite a dilemma. Do I wait another four hours to take medicine and risk becoming a plugged-up-hacking-sniffling-snot factory? Or do I just take some more medicine now and risk even more absentmindedness/that head-floating-ten-feet-above-me feeling/lapsing into a coma at my desk?
