when you are dealing with C, that is pretty common. have you tried miralax? I stir it in my coffee (don't shudder, everyone, it is the only way to get stuff moving for me) and life is good! you can buy it over the counter, but I have great insurance, so I have an rx for it and it is quite cheap.
if you have more questions, feel free to email me. you can find folk's email addresses in their profile if they chose to include them.
take care, yp
