It's about preparation. Approximate gut motility for a healthy adult on a light diet is about 48-60 hours. So, stop eating 3 days before you leave, poop out all you possibly can before your 3 day period starts. Drink about 500ml water per day in the days leading up to the 3 day period. It wouldn't hurt to prep with a mild laxative to remove as much gut content as possible.

Once the timer starts, start eating small amounts only after the first day. For water, about 500ml per day. The good news is that what you pee out can't take much more space than the fresh water you drink.

This assumes you are relatively sedentary. If you perform manual labor during the 3 day period, you'll need to increase water intake, and possibly food intake, to avoid exhaustion.

Canned tuna. It's very dry and almost all protein so most of it gets absorbed by the body and you'll be pooping neat little bricks.

I haven't seen any comments suggesting a plug, so I guess it'll be me. Try using a butt plug.

Why do you need this?

My only advice would be to have a back up plan. If you fail to plan, you plan to fail, and there's no guarantee you won't get an unpleasant surprise. You say you'll use the toilet if you're about to shit yourself, but what if you can't make it and do end up shitting yourself because you put it off so long?

I really wish I knew what I did in the past to achieve this. Depression and poor eating habits?

This has to be a kink thing, one of the weirder ones. Holding a plug, not sweating, because it is not wished?

Else it is something illegal. Drug mule, crossing a border which would either make the drugs visible, or maybe another crime to not leave obvious DNA traces. No sweating to not look suspicious on control? Not much stuff to disguise the longer travel?

Just wanted to say I was here for this.

Please post again after your ordeal, OP.

It’s ok. He/she/them will understand that people do poop. They aren’t worth it if they can’t Accept this

Honestly, I’m just commenting to say I was here.

One of the more interesting posts I've seen here

Im dying at the urgency. "Guys tell me how to not shit for 3 days AND DONT ASK QUESTIONS DAMNIT"

You doing some sort of Mr. Beast challenge?

Im just posting so I can see my username on one of Whang's videos one day.

Tbf, there's a difference between knowing instinctively that someone poops and being first-hand witness to the godawful stench of post-chipotle bowel movement in an area with poor air circulation (AC aside).

Crush is definitely involved though.

If it's important you can easily just not eat for three days. Otherwise, there's nothing you can eat that will be safe and prevent you from pooping.

I'm honestly more curious about this than I was about any of the locked safes.

I wonder if doing a colon cleanse beforehand help? Similar to what people do before a colonoscopy.

Also, it is an odd request but I’m now fully vested in your post to see what others suggest.

MREs. Particularly US MREs. You can eat em as much as you want and you won't have to go for a week.

Fear the end of the week, however
