<human>: Could you distill the essence of the text into 1-3 sentences?

I've been having stomach problems for over a year. I've gone to the doctor quite a few times but today was my first CT scan to see what was going on. For those of you who have never had a CT scan of the stomach, it isn't a pleasant experience. I had to stop eating and drinking all liquids (including water) at 10 am. 

Once I got to the hospital and was in the waiting room, a nurse brought out three giant containers of liquid. There were times written on the top: "Drink me at 2:20, Drink me at 2:35, and Drink me at 2:50." They were each 450 mL. The purpose of drinking these contrasts was so that my stomach was more visible under the scan. 

The first went down pretty well, although it tasted like battery acid. After not having anything to eat or drink for about 4 hours, anything sounded good to me. The second one was easy, until about halfway through when I could feel the chemical substance start to fill my stomach. The third one was basically impossible. My stomach was so full and I couldn't get the stench of battery acid out of my nose. 

The CT scan went fine and I was on my way home when my stomach starts to grumble. They gave me water and a granola bar after the procedure so I was feeling a bit better. But this wasn't a normal stomach growl... this was one of those growls that you knew was going to lead to a satisfying, grown-ass man, full-blown fart. 

I'm on the high way going back home and this fart is going to save me. Just as I let this massive monster rip, I hear a blood curdling liquid expel itself from my butthole. Oh... oh no. Oh god... Did I... Did I just? I slowly reach my hand around the back side of my pants. Wet. I shit the contrast all over myself. I sat with my shitty pants all the way home, too embarrassed to get out and see if you could see it through the back of my pants. Needless to say, fuck CT scans.
<bot>: drank 1350mL of contrast for a CT scan on my stomach, ended up shitting liquid on the way home.
