The pills were first advertised in the local newspaper. The advert was simple: a yellow smiley face held in a hoof of a pony. Underneath the image were three words:
YOUR HAPPINESS, GUARANTEED!
Naturally, Pinkie just had to see if they worked as promised. After all, happiness with no side effect was a tempting offer.
Thank you so much to Troposphere, Seraphem, and Manifest Harmony for prereading, editing, and providing general support!
This story is not about mental health medication, it was intended as a thought experiment about happiness. Also, We Happy Few came out a lot later than when I wrote this! I'm well aware there are similarities, but I wrote this quite a bit before it came out.
