Wow that doesn't sound like something I'd be "open" to at all.
When you need it, it's not so much of a choice. It's how (or one of the ways they check your intestines for leaks.
For those who don't know.
They have you on a very strict diet for 48-72 hours while consuming medications to clean you out. Then then insert an enema, they then lay you down and fill you with a cleaning solution and then stand you back up. Then they do the same steps with barium which is a chalky looking white liquid, it coats your intestines. Then they fill you with air and take x-rays of your intestines.
And when your doctor through this procedure is this sexy blonde with an Australian accent, it ruins all Australian women for you.
You also fart white powder for days after.
