The colonic might be okay for the lower third of the colon, but it's not going to be sufficient to clean out all the way to the ascending colon, where, incidentally my own tumor was located. Better to put up with the bad taste for a few short minutes. It's really comical to watch me prep for a colonoscopy. I spend a lot of time looking at myself in the bathroom mirror, talking out loud to myself as I build up the courage to drink the old phospho soda. Best wishes for your test.
Happy and healthy 2007,
