Sick and Tired .... or just stupid?

So all day today I've been feeling really lethargic, spacey, and just so tired I'm just not with it. I thought I was coming down with something or trying to fight off something. Here's how bad it was: I don't remember driving to work. God was definitely watching over me.

Let me back up a bit. I have headaches. Not just little ones. Big ones, recurring ones. Frequent ones. I take a lot of medication, some that makes me drowsy, some that give me energy, all to ward off these headaches. Sometimes it works. To keep these medications straight I purchased one of those little pill thingys.
Adam likens me to an eighty-year-old woman thanks to this little box. Nice, huh? This is supposed to assist me in knowing what pills I've taken, when to refill pro actively, and also aids in not having to open 4-5 bottles in one sitting each morning and/or evening.

When I got home from work tonight, I sat down to refill this nifty little case only to realize that this morning when I should have taken the meds for Tuesday AM, I had taken the meds for Tuesday PM. Not Cool.

Yep, it helps determine I 've taken pills, but does it help just plain stupid?
