Ran my first test enema with Bronner's Lavender soap. I used 1 tsp per 1200 ml for a very mild soapy water solution. Of the 3.6 litters mixed, I took and held 3.1 liters using the complete insertion of both balloons of the latex double balloon catheter.
It provided a mild kick but no severe cramping or excessive discomfort from a burning sensation. A 15 minute hold and two subsequent rinses completed the procedure.
