Alka Seltzer

I was wondering if this is dangerous or if anyone has tried this:

Before receiving a plain water enema, insert two Alka Seltzer tabs into your rectum. If this isn't safe, can you suggest another recipe that gives you a nice rumbley churning feeling?

This sure does work!! Lots of gas and bubbles. Not much different

than using a 2 liter bottle of ginger ale or some other carbonated beverage. Many years ago a suppository by the name of Vacuettes could be used in the same manner and they were easier to insert. I believe they are no longer being made, although I think some other suppositories that react with water causing CO2 gas may still be available. Have fun!
