Around here there's something my phamacy calls the Medicaton Roll (at my mother's job they call it Baxter, somewhere else they called it ATC sachets). It's basically a roll of small sachets containing pills with a date and a time (and your personalia, and a list of contents) on it. So if it says 13-12-2017 9.00 you know you'd have to take the contents of that sachet in 6 minutes.

I've accidentally taken too many meds, or the wrong meds, before. I'm very careful about filling my pill organizer - if my concentration is bad it might take 2 hours, othetwise about 20 minutes - but I've taken morning meds at night and the other way around (which made me reallly drowsy, slept half the morning or afternoon whenever that happened). Or accidentally swallowed 2 compartments instead of 1 and stuff.
