I have the same problems that you do and will be requesting a colonoscopy at my Dr. appointment today. I'm totally worried that it might be something horrible although I'm trying not to freak myself out. I can't remember the last time I had a poo that wasn't soft and narrow so I'm thinking "OH God, did I let this go too long". I've always just blamed the gas and weird poo on the IBS. Hopefully we are both OK!!! I have a tendency to worry about the worst. Good Luck.
