Some of you might want to ask for HalfLytely. Its half the amount and not quite so bad tasting as the NuLytely and GoLytely sewer water.
Its no picnic, its a bowel prep, BUT, at least I could get it down altho w/my gastro's blessing I took less over a longer period of time. In other words I took twice as long to get each of the two "cleansings" down. Instead of an hour per dose I took 2 hours to get each dose down.
That greatly reduces the nausea caused just by having to get so much volume of liquid into your tummy in so short a time.
And, Ellemmy, if I were you, once this scope was behind me I'd be asking around and checking around to see if I could find a gastro w/a little more respect and consideration for his/her patients. This guy may be darn good - BUT - he sounds like a real jerk to have to put up w/and rely on.
He is either egotistical enough - or dumb enough - to badly handle the insurance issue w/you rather than being smart enough to leave that up to his staff.
