O, JOY.
I couldn’t finish that junk; I chugged as much as I could without my body just slamming the whole process into Reverse, and there was no getting any more in. Flavor packets do next to nothing.
But, two things I did that helped me greatly: I went on a water-only fast a day before I had to begin the prep. So, I didn’t have a whole gut full of food to clear out. It still was a drag, but maybe less of one that it would have otherwise been.
I can’t do that. I have meds to take four times a day and I have to eat something when I take them.
So I avoid colonoscopies.
