It's definitely a challenging test, but I've had it 3 times and I'm still here! I'd have it again tomorrow if I needed it.
Here is a video showing someone having the procedure. (It also shows the insertion of he 24hr PH monitor, so disregard that.)
Bill, our moderator and professional GI test-taker suggests sticking your tongue out and holding it between your teeth in between swallows to avoid extra swallows. You're supposed to swallow only on cue. Those extra swallows make the test take longer.
You'll do just fine!
