Had a similar thing once. Long fishing trip camping in the woods. My body refused to shit. Until driving home. Thank God it was a public restroom because I shit what looked like a beef Wellington. There is no way that was flushable. Felt like it tore my asshole apart. It was quite the ordeal.Years ago I ate a whole pizza and a 12 pack after a long day.
I didn't shit for 10 days, thought I was going to die, no natural remedies were working. It was to the point I had a weird taste in my mouth.
Drastic action was taken and the shit I took is the all time record setter. I was afraid to flush.
So much corn..
