It doesn't involve enemas, but I have found a cleanse that DOES work well, and cleans EVERYTHING out.
First, you have to clear the stomach.
That is done by going on a liquid diet with no milk, dairy products or alcohol for at least 24 hours, Water ONLY the last 8 hours.
To start the procedure take 6 bisacodyl (Dulcolax or generic) tablets all in ONE dose with plenty of water.
Two hours later Open an 8.3 oz bottle of Miralax or generic ( Does come generic) I use about a 12-16 oz cup. Fill the cup with cool or cold water.
Put in two dose caps full of the Miralax in the water and mix it well. Drink that over no more than 15 minutes, I find it flavorless and easy to take.
Then, every 15 minutes put ONE dose cup of Miralax in that same amount of water and drink it as quickly as you reasonably can. repeat that every 15 minutes until you have had two completely clear bowel movements.
About an hour after that use ONE bisacodyl(Dulcolax) suppository, just to be sure you got everything.
Be prepared in case you DO have to drink a dose or two while sitting on the toilet.
Do that and your digestive system is washed out
