I use laxatives, suppositories and enemas for chronic constipation. However, I also use them for pleasure, also. If I am going for a total clean out, I usually start with a purgative dose of a strong laxative the night before. This might be two tbsp of castor oil, or 4-6 bisacodyl tablets. The next morning, after the laxative works, I drink a bottle of citrate of magnesia, followed immediately by up to four bisacodyl suppositories. I go about my chores around the house as I wait for my suppositories to kick my colon into high gear. That usually takes 45 minutes to an hour and a half. Normally, I just sit on the toilet as the urge to go becomes strong, although if I'm in the mood, I may diaper up and wait for the suppositories to force a BM. Either way, once I get the laxative and suppository induced BM, I start my first enema. I mix it up and fill my 4 qt open top bag when I feel that the suppositories are becoming impossible to hold, so it is hanging and ready for me. I only take 2-4 qts for enema #1. My second enema is the full 4 qts. Keep in mind that I have a bottle of magnesium citrate working to flush out my upper GI tract, and by the time I've fully released enema #2.
I pull on a Depends and relax around the house, surrendering to the diarrhea caused by the magnesium citrate. I fight the urges, and try to get to the toilet before I mess the Depends. Once the artificial diarrhea subsides, I mix and take one or two more SSE's, then I mix two or three salt and baking soda rinses. I have never needed more than three before the last one runs clear. I only do this two or three times a year, just to start over with a fresh colon flora. Although I do enjoy the process, it is time consuming. Not counting the overnight hours as my laxative works, the whole process takes 12 to 16 hours from start to finish. Finish defined as safe to venture away from the house.
