bowel preparation
"I have had 9 colonoscopies over the last 15 years, and of all the preps I have used, I dislike this one the most.  It is very effective at it's job, but it is also too effective, for I have had loose bowels and watery discharge for over a week.  I will report this to my doctor, who I hope will advise his patients to use some other form of prep."
