4:10 pm. House of poop. Back at the hotel we spread out the preparations for tomorrow's colon X-ray exam: a bottle of magnesium citrate solution (4 pm), Ensure liquids for dinner (6 pm) and breakfast, 4 laxative tablets (7 pm), a suppository (10:00 pm), and at least 8 ounces of liquid every hour from 2 - 10 pm; nail clippers and nail file to prepare poking finger for suppository; and Depends diapers for sleeping protection and possible use during MRI.
