The Day-Off Pill
This product would be marketed as a series of pills which simulate the symptoms of different diseases for a short period of time (about an hour or two). You can take one of these pills when you want an irrefutable excuse to avoid something.
There will be a wide array of simulated illnesses:
The Head-cold
Simulates a stuffed nose, sneezing fits, and red watery eyes.
The Cruiseline
Makes you look extremely green around the gills and sweaty.
The Plague
Gives you that stylish heroin-addict look.
All of the above will also give you an elevated temperature for a short period of time (which shouldn't cause significant damage to your body).
