It varies depending on how my colon is working. Clock starts on the day there isn't a bowel movement. On the third morning if there is not any action then it is time for an enema.
I was alternating between a 3 qt soapy enema and a 3 qt baking soda solution enema, but this week
I decided to use soap again. I think it was a better enema, so I will continue to use soap, Dr Bronner's peppermint, for my cleansing enemas. I use either a Foley tube or a colon tube for these enemas. I start and stop the flow to allow the water to disperse through my colon. Typically between five to seven minutes total.
Activities permitting, I also indulge in a smaller - 1.5 qt - baking soda solution enema on Sunday mornings. This is a retention session using a double balloon tube. Wifey massages my abdomen during the retention. I get to relax and relish the sensations. We use a massage table for this, height adjusted so she is comfortable while she massages me. She likes doing the massage, which is nice.
