The Secret Triwizard Challenge

You pick the second potion. It reminds you of a dessert, all in one potion. It's a safe choice because it doesn't appear to be very magical, so surely it won't hold poison.
You take a sip and taste the chocolate, plums, and... something else. Something... bitter. Something...
Immediately, you fall to the ground, convulsing. Whatever was in that thick potion-
Oh. WAIT.
"Drink either and die through thin and THICK."
Well, CRAP. You should've realized that. Now, you're on the ground, barely breathing, barely conscious, about to die. You close your eyes...
------------
You wake up in the hospital wing a few days later. You're very frail, but you're alive, thanks to the quick thinking of the broom monitors, who got you to Madam Pomfrey in time. You won't, however, be alive for long because a furious Professor Dumbledore stands before you. You'll be expelled for sure.
But that's not the worst part. You'll have to live with the fact that you lost the race because of one stupid decision. You were so close. YOU LOSE!
