Exactly. The extra $5 I paid was for four chewable simethicone tablets that I had to take (with just a glass of water) in between the two Sutab doses. That was to eliminate gas buildup in the intestine (which is why some of those preps cause a bloated feeling).
Very happy with the whole process, and even happier that this was, in all likelihood, my very last colonoscopy ever!
Hmm maybe I should ask about simethicone. I generally feel like my insides my burst but I always thought it was too much liquid. I *definitely* do not care if the cost is covered if it can keep me relatively gag free.
