Thanks to both of you who responded, and thanks for the encouragement! :-)
I didn't take the 4th ES, I instead drank some liquid minerals/vitamins
with room-temp water and am about to drink some warm lemonade. Mostly what I
got out this morning was very loose diarrhea, a few pea-colored things
in the first couple of trips to the bathroom. I guess I'll just keep on
doing flushes till something more substantial moves! At least time I didn't
throw up, which was a big step for me! :-)
