IrishGuy,
I had very similar problems. I had my RC June 2007. Even though I have an Illeal Conduit, they still use the intestine (Actually they tried to do a Neo, had problems so they had to switch to Illeal Conduit. So I had two sections of intestines taken out).
I had the bowel movement problems and then in June 2008 I had my gall bladder removed (now I have no more bladders). This compounded my bowel problems.
The good news: I change my exercise program and my diet completely (Jan 2009) and now I am regular.
I cut out red meat, sweets (pastries, ice cream, and candy), and pop (diet Coke and Diet Pepsi).
The red meat cut out was recommended by my doctor for the missing Gall Bladder contribution.
Exercise is now 60 minutes a day six days a week.
This combo is what finally worked for me.
Take Care
Rick
