Did I take my pills?

As I look around my bathroom sink in the morning, half- asleep, I see my toothbrush and toothpaste, deodorant, allergy medicine and vitamin, and razor and shaving cream. I work my way around the counter performing each task, but on some mornings when I'm particularly low on sleep, I start second-guessing myself. Did I already brush my teeth? Yeah, my mouth tastes like toothpaste. Did I already put on deodorant? Yes, my armpits are slimy. The hardest task to comprehend is whether I've taken my pills. The sink could be wet from brushing my teeth, or I could be juggling a memory of having taken them yesterday.

Proposed is an extremely simple device placed on a bathroom counter next to whatever task is to be remembered. It would be about the size of a baseball or perhaps half the size of a coffee cup. It would have a large button on the top, designed to be very rugged. Upon completing whatever task associated with the device, the button on the top would be pushed once. The device will illuminate for an hour and automatically shut off, ready for use the next morning.

(...or I could get more sleep)
