bowel preparation
"OK, THIS IS "OFF LABEL," BUT I THINK USEFUL INFO, and the only way to get it in is  pick some med and "review" it.

I started them at 50.  

Prep is to get everything out so they can see any growths.   My experience is a med at night, for solids, and another in the AM to flush any colored liquid.  But my second 2 yrs after, the PM dose was near impossible to keep down, the AM came up immediately.  They tried both a small bottle to mix in 8oz of some clear liquid, and a gallon jug to fill with water, no luck.  Then I thought of prune juice.  Clear out solids, then the real med in AM for a clear flush. With the PM irritation missing, the AM med dose stayed down.  Works perfectly.  Still no fun, but much less nasty. Med stuff below made up. "
