What’s sad is I’ve been so constipated before (1 1/2 - 2 weeks of no pooping) that I drank a bottle of mag cit. And took some ex lax. And drank some miralax. And that still didn’t do much for a few days.

I’m in solidarity with OP on this one.

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.
