Metamucil is supposed to help you form bulk while helping keep people regular (original texture if you get a generic works best for me, you might mix with a little G2 for flavor), but you must drink enough water with it to prevent stool from getting too hard. I definitely
can say from experience that stress
can affect both bladder and bowels, including giving frequent diarrhea. I believe you have IBS, as I do, it can aggravate the more active side of IBS when you are overly stressed.
