Mage, 5 enemas in a 3 1/2 hour period are way too many on a weekly basis! I would suggest an initial cleansing enema first using a filtered or warmed bottled water saline enema - one teaspoon of Sea Salt or plain table salt to each pint of water, or 4 teaspoons for a full bag.
After releasing, follow with the coffee enema. You shouldn't have to take cleansing enemas after your coffee enema, in fact, they may dilute the coffee's effectiveness.
