Glad to hear that!
The jug of hideous goop that they make you drink for hours was the worst part--even more than fasting from solid food for a day. (Oddly enough, the fast didn't impact me much at all.)
So, I was talking with one of the nurses while we were waiting for the doctor, and she mentioned there is a new prep out now, that isn't nearly as hideous, and you drink a lot less of it.
The problem is that because it's a newer prep, it costs more than the original junk. Hence, most insurance companies are bucking it, and only paying for the original nightmare prep.
(I actually puked up the final third of the prep, so was unable to finish that last third of the bottle. ) But apparently I drank enough of that carp to do the trick.
(I also can't stand the "one size fits all" approach with the prep. If i managed to keep down 2/3 of it and had an excellent prep (as the doctor wrote in the patient notes), then why subject everyone to that entire jug of hell? I'm hoping that in 5 years (when I have to be tested again), the price will come down so that I can use the newer stuff. I'd even pay out of pocket for it.
I guess he is just like a kid, when he won't try a new food I just have to trick him into eating it, then when he likes it I can tell him the truth!
