I think they could do pretty well just not adding bubble gum or whatever nasty flavors the prep has. Sure it'll still be unpleasant and salty, but burping up that nonsense all day really doesn't make it better.

Depending on the doctor some are now recommending getting a tub of miralax, mixing it all into gatorade, and using that for prep instead of the prescription stuff.

Still sucks, but at least it isn't a disgusting flavor, although I haven't had a desire for blue gatorade in the last 3 years

I do this, I have gone through 10 Costco tubs so far in my 1+ year of suffering from chronic constipation

By far the worst part. By far.

Though having to push out a huge fart at the request of the nurse while they stare at you when you wake up is a close 2nd.

I've never heard of that. Is it standard?

When I got my second, I had a bidet and it made a huge difference. That and a bit of vaseline to prevent too much irritation. It's an uncomfortable process so taking every win you can saves your sanity

This may be regional but I just had pills. It was fine. My first one had that terrible salty liquid and I cannot stand the salt. I had a very hard time with it, despite adding some flavoring. I just can't drink salt water. So my second one I got pills and it was miles and miles easier. Now the hardest part is fasting for a day.

I really didn't mind the prep experience. I can't say it was pleasant, but not a big deal. For me the worst part is the risk of perforation: it's rare but adds risk to the procedure.
