You’re putting so much effort to avoid pooping… but you should put the same effort into making sure that once this whole thing is over, there’s a toilet you can sit on for a few hours without being interrupted. If I was you, I’d choose one in advance and call there for a reservation.
Since you added the hours left, the whole (not-)pooping thing sounds way more serious now. Damn, maybe if you added some countdown timer, I’d stop laughing.
I need to survive for 3 days without pooping, and eating as little as possible. I can pee, but not very often. It can't take up too much space. What food do I pack?
Please don't ask why I need this....
