I've had the same problem since the day I was born. It used to be that I only had to go 12 hours without eating anything if I had a social engagement; in the last few years--I'm in my 70s--it's become 24 hours that I have to go without eating and I just can't go that long without eating so no more social life. And the gastroenterologists have no answers other than "Some unfortunate people are just born with bad digestive tracts."

I looked on the Nutritional Frontiers website but didn't see a "fiber" product; is it maybe one of their "G.I." products? Thanks for any info.
