Dude, I know you can't say why, but I sincerely hope you come back after your...excursion? And update us all with the results. And may e tell us why when you have the chance.
Just coming in here and saying you can't shit for 3 days. What on earth is this.
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....
