<human>: Can you summarize the given text in a few sentences?

This one goes back to when I had surgery to get my appendix removed.

The antibiotics I was given during my stay at the hospital and at home caused severe constipation. As such, it was perpetuated by the fact that I had my abdominal region sliced into (about a 2" slice) and could not flex my abs to 'push' a crap out.

During my 6~ day recovery I literally just sat on the couch and ate, trying to get my strength back. I got a bit worried at day 4, I was quite a healthy eater and was well aware of my daily (sometimes 2x) bowel movements. I decided to take some laxative chocolates, 2 servings, before bed. The next day, nothing. More frustrated, bloated, and full of food, I eat the entire box of laxative chocolates (16 more servings) before bed.

The following day I am awaken by a sore neck from sleeping on the reclining sofa. I take a sip of my coffee and realize that something is very wrong. I rush to the toilet.

What followed was the most despicable, heinous, abomination I have witnessed, and can only be aptly described by quoting Lovecraft :

"The Thing cannot be described -- there is no language for such abysms of shrieking and immemorial lunacy, such eldritch contradictions of all matter, force, and cosmic order. A mountain walked or stumbled. God!... the Thing of the idols, the green, sticky spawn of the stars, had awakened to claim his own"

You know when you are playing Tetris and get a bit distracted, next thing you know you are full to the top, but pieces are still dropping?  Well, I lost.  Game over.  I won't even get into the chore that was getting that mess down the toilet.
<bot>: I got surgery, constipation, almost a week of not shitting I desperately eat a box of laxative chocolates, play toilet tetris, and lost.
