I have a barium swallow for eleven AM tomorrow, and have to stop eating/drinking in twenty minutes.

I'm honestly tempted to cancel.

It's not the test itself I'm afraid of. I know it's painless, just tastes funny.

It's afterwards.
I keep reading testimonies and reviews from people who reported horrible stomach pain a week afterwards, complete inability to pass stool, having severe pain a few hours after the test... It's enough to make me bail out. I keep seeing threads here saying "The test was fine!" but nobody is talking about AFTERWARDS.

I was under the impression I'd just feel kinda queasy but now I really don't know!
