Hi Katherine,
No, not for me. Nearly 20 years ago, i started putting a heaping tablespoon of psyllium (metamucil sugar free smooth texture orange, which I could get at Costco) in a big shaker bottle, with cold water and lots of ice. I would chug it on my way to work. It was recommeneded by one of my docs when I was dealing with an acid/ulcer-prone stomach, because it coats the stomach. It never gave me diarreah nor was I ever constipated. Regular like clockwork each morning. But moreso, no raging stomach aches.
(The shaker bottle and ice help keep the mixture liquid while you drink it. Of course otherwise, it starts to thicken jelly-ish if it stands too long -- a lovely thing in the tummy, not so lovely in a glass.)
