I'm missing 2/3 of my intestines, gall bladder, and appendix. My toilet and I have an intimate relationship and the term "shit the bed" isn't just a figure of speech for me. Good times.
Very often to be honest: I always take a shit when I wake up in the mornings, another one at the office, then another one coming back home and the last one a couple of hours before the bed. Of course there are some exception but normally this is my anal routine.
