i skipped the salad for a few days and noticed the poop firm back up again. i had a giant salad last night for the first time in a few days, minus beets, and in two courses, and the result was a return to the mushy poop, but without the reddish hue.
i'm totally convinced.
but, i have a phone appointment very soon to talk to the gp about a fit test, to be sure.
