I posted this one before
Try a solution of the following: 16 ounces glycerine, four ounces of Dr Bronner's soap (any kind) and two ounces of peppermint extract with three pints of water added to make about a half gallon of solution. Maybe you should divide this into two separate doses of one quart each.
Combine the ingredients in a large pitcher or pot. They may be hard to get evenly mixed in a bag, especially a closed top bag. Add the 3 pints of water to the pitcher first, then the peppermint extract and mix, then the soap and mix, last add the glycerine. They mix up easier in this order.
BE PREPARED FOR A VERY ROUGH RIDE AND MANY RETURN TRIPS TO THE TOILET FOR 12 HOURS AFTER EXPELLING! THIS ONE IS NOT FOR THE INEXPERIENCED. YOU SHOULD HAVE USED EACH OF THE INGREDIENTS INDIVIDUALLY AT SOME TIME PRIOR TO DOING THIS SO YOU HAVE AN IDEA OF WHAT TO EXPECT.
Have a few rinse enemas afterward.
You will both taste and smell the soap and peppermint from this enema.
I bet you can't even hold it without a double balloon rectal catheter pumped up tight!
