The symptoms you describe are quite similar to the ones I have been "surviving" with for over 17 years now. They became truly exaserbated after my first child was born. I too have more trouble with frequency of movement than the acctual consistancy of the stool, although I can run the gambit of C to D during one morning's cycle of evacuation. Yes, everything is worse the day before and the first day of my period. I also notice a lot more gas and irritation at ovulation usually. The Bentyl didn't bother me too much, but I didn't help much either. What really whalloped me was Elivil. Talk about cramps and D. I did the Prozac thing too. It sort of deintensified the symptoms some for a while, but then it seemed to level off and I choose to discontinue it rather that up the dosage. It didn't make me drowsy or anything, though. I'm not sure where all the hype about Prozac got stated really, but I don't like taking chemicals unless there is a really good reason. As you say, it is always sort of reassuring that someone else is experiencing thing similar to yourself, since its not something that comes up in normal conversation and you don't just ask around at the office... I think natural food type fiber and water my be our best friends in achieving normal evacution habits. but it never stays perfect :-{
