I have an odd schedule (work nights). Usually go to bed about 7 AM usually wake up between 10 AM and Noon and go. The 10 AM to noon wakeup (but not the BM) was a 'feature' of my schedule pre-op. When I get up at 3 PM I usually need to go right now so sleeping in is not at option.I would be so aggravated to wake up in the middle of the night to use the restroom unless there was a pregnancy or infant involved. But the fat consumption and calcium to control it all is something that I am planning on remembering.
