I would have a protein shake with Blueberries first thing in the morning along with a scoop of psyllium. Things move through every time except once and I was prepared. We would get thrown off the island but could get back on if ready within the allotted hour. I carried a small enema in my coat pocket. They wouldn't give us anything, so I met my needs in 8 minutes. A small shot in the rectum did it.
