Diarrhea or Constipation?

You've gone and done it; you pissed off the god of poop. As he waves his divine poop knife to curse you, he gives you a choice: diarrhea or constipation?

The details are thus:
For each option, you will be cursed for a full year.
Once per day, only once, randomly, you will have a strong urge to defecate.
It will not happen while you are at work or school, he's not a monster.
It could happen anywhere else--home, car, shopping, the theater, sporting events. Even sleeping in bed.
If you choose diarrhea, you've got 90 seconds to find a toilet. You will have to clean the toilet after. If you don't make it... well, you'll need to clean more than that.
If you choose constipation, the immediate urgency isn't there, but the longer you put it off, the more it hurts to wait and the more it will hurt to pass it. Wait too long, and there's a real possibility the strain might cause you to blow a gasket and have a mini stroke or a minor cardiac arrhythmia. Either way, the smell is utterly foul.
Because he's a benevolent god, he gives you a third option too: one of each, for half as many days.

Which do you choose?

This hypothetical may possibly be inspired by the side effects of my cancer treatments.
