Put a little over 1 quart of clean water in a pan and bring it to a boil. Add 2 flat tablespoons of coffee (or the coffee amount that was prescribed for you). Let it continue to boil for five minutes, then turn the stove off, leaving the pan on the hot burner. Allow it to cool down to a very comfortable, tepid temperature. Test with your finger. It should be the same temperature as a baby´s bottle. It´s safer to have it too cold than too warm; never use it hot or steaming; body temperature is good. Next, carry your pan or pot and lay an old towel on the floor. If you don´t use an old towel, you will soon have many old towels since coffee stains permanently. Use another bunch of towels, if you want, as a pillow and bring along some appropriately relaxing literature. Pour the coffee from the pan into the enema bucket without getting the coffee grounds in the cup. You may prefer to use an intermediate container with a pour spout when going from the pan to the enema bucket. Do not use a paper filter to strain the grounds. Put your enema bag in the sink with the catheter clamped closed. Pour the coffee into the enema bag. Loosen the clamp to allow the coffee to run out to the end of the catheter tip and reclamp the bag when all the air has been removed from the enema tubing. Use the hook to be used for this purpose to hang the enema bag at least two feet above the floor; on a door knob or towel rack. The bucket can rest on a chair, shelf or be held. Do not hang the enema bag too high, as on a shower head, because it will be too forceful as the coffee rushes in. It should flow very gently into the rectum and distal sigmoid colon only. This is not a high enema or colonic. Allowing it to go well up into the colon may introduce caffeine into the general circulation as though you had taken it by mouth. Lie down on the floor on your back or right side and gently insert the catheter. If you need lubrication, food grade vegetable oil such as olive oil or KY jelly should be fine, unless you are chemically sensitive. It is generally a good idea to avoid petroleum products.
Gently insert the tube into the rectum a few inches and then release the clamp and let the first 1/2 of the quart (2 cups maximum) of coffee flow in. Clamp the tubing off as soon as there is the slightest amount of discomfort or fullness. Do not change positions or use an incline board to cause the enema to enter further into the colon; this defeats the purpose of this type of enema. Try to retain the enema for a minimum of 12 or more minutes. Sometimes there will be an immediate urgency to get rid of it and that is fine. It helps to first clean out the bowel with a water-only enema, which is immediately emptied in the toilet, so that next time around you can hold more of the coffee enema longer. Never force yourself to retain it if you feel that you can't. When you have clamped the tubing, remove the catheter tip and void when you have to. It is best to hold it for at least 12 minutes each time. After you have emptied the bowel, proceed with the remaining 1/2 quart and likewise hold that for at least 12 minutes, if able, then void.
