Thanks everyone for your responses. I often think that my 2 obligatory cups of coffee in the morning "rev things up". The initial time that I "go" is very normal consistency. A little later on in the morning I often feel a sudden & urgent need to "go" and have diarrhea. It's that second part that is very unpredictable. Recently I went for a walk in the park behind my house and did a brief jog during the walk. There are port-a-potties in the park just during the summer (for the disc golfers) and I felt a very slight urge to go, but thought I could make it home (I just thought it was gas). Well, as I approached home I had to pick up my pace and take a short cut. Needless to say I had the mother of all "accidents" and was absolutely horrified! That had not happened to me since I was about 8 years old! I had a huge mess to clean up that included major laundry. Thank goodness I was near my house. I can never take for granted that what I think might be gas could easily be more than that. I can never take that chance if I'm out somewhere.
I'm sorry if this is all too much information, but I am certain that I'm not the only person with this issue. Typically I am finished after the twice per morning "events" so that's a blessing I guess.
