when i was in icu after a majour accident, they gave me a laxatative a couple of times. its was incredibly painfull in a shit related way. your insides feel like you ingested a bucket of tabasco sauce.
and try shitting when lying prone in bed.
the whole thing is so traumatic that all shame is out the window when they have to clean you up afterward. i mean, i had like a bedpan, but that thing would overflow and what not.
AND i was in pain because of the accident. i pooped midday, slept till evening to eat something, slept till next morning, it was this exhausting.
