My symptoms were diarriah for the first 4-6 weeks, but within the last 2 days have had 2 bouts of constipation. I am also taking Citrucel powder once at night. I think it may be time for me to go to 2 times a day, and then up to 3 times a day per the instructions on the Citrucel container. My only guess is my body has now absorbed and gotten use to the one dose a day and needs more to make the diarreah and constipation obsolete and let my bowels stabablize. I have a return appt. with my doctor on the 2nd and have somewhat the same question. Let me know if you get some answers.
