Never had that. If you hadn't posted a pic I was going to ask if it was Cola and sparkling water!...haha I don't eat meat decades and decades and decades...lol so I don't have that buildup of meat stuff. Did a colon cleanse once, where I drank some stuff to clean out the colon...YIKES Couldn't believe the yucky stuff that came out. looked like it came out of the sewer....LOL But I ate meat until I turned 21, cause I didn't know any better. So anyway. Never had a colonoscopy either and this body is over 70.
