bowel preparation
"I wish I would've read this group prior to starting my prep.  I've had Crohn's Disease for 19 years and have had numerous colonoscopies.  Currently, I'm in good health and my colonoscopy tomorrow (hopefully is just routine.  Preponik sounded promising.  Less nasty liquid to drink.  Hooray.  Except that I drank magnesium citrate at 7pm last night and Preponik at 9am and 4pm with more than the recommended amount of clear fluids and hardly anything has happened.  It's now 6:15pm and I just talked to my GI and had to drink an extra bottle of magnesium citrate (a fleet enema doesn't clear our the upper colon).  If it doesn't clear out by 2am, I can't do the colonoscopy tomorrow.  Seriously?!"
