If anyone here is up for disrupting the medical field: please come up with a colonoscopy-equivalent with a less awful prep experience.
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.
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.
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
