Use anti diarrhea medication, for example Loperamide, it's available in every normal pharmacy (found it in France and Germany, no idea where you are). It will basically numb all your muscles in your gut and it will become impossible to poop.

For three days that should be fine, but you should reduce your food volume a bit.

This is unhealthy and stupid!!! But it works and is not crazy dangerous for your body.

P.S.:I guess you should just overcome your social fears and poop like a normal person.

I'm going to tell my descendents this was the origin of the phrase "I shit you not"

I was here when the no-shit post jump started the popularity of this platform. My children will be so proud

Please post again after your ordeal, OP.

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 have the solution because I too have been in this exact situation, but you can't eat much or you'll be extremely uncomfortable.

The day before you go, drink a full bottle of magnesium citrate. This will cause liquid diarrhea and completely empty you out. This is used before Colonoscopies to give the doctor a clear view.

Then for the next 3 days eat very little while taking 3 immodium each day.

You're welcome.

This is like some bizzaro 90's sitcom. "Quick, I need your help to not poop for 3 days! No time to explain!"

I’m so happy I’m here!

Update plz?

Wut

Take Iron supplements and eat noodles, the nissin soba classic. Also, hardboiled eggs. Backs me up every time.

Oh my God, I have so many questions.

Just take the dildo out for 5 minutes man, it's no big deal

Breast milk has very few undigestible solids. Just saying.
