Hi chikitta,
I am no expert for your problem with gas. I can relate to it because of my own experience with a similar problem. I have been using coffee retention enemas for many, many years and did not have problems, Recently I changed my cleansing to a smaller volume coffee enema and quit my pre-coffee cleansing enema and also my post coffee cleansing enema and start having very serious gas problems with extreme pain.
After many different trials to overcome this problem, I found that the saline solution enema that I took before the coffee enema was part of the problem. I replace it with a 2 quart soapsuds enema and a great part of my problems got cured. Second I replaced my two small retention coffee enemas with my old standby of 1 quart coffee with 1 to 2 teaspoons of Epsom salts and retain it for 20 minutes. All my gas problems disappeared. I do this once a week with a day of fasting. I also do the protocol for 7 days once every few months or whenever I feel toxic. Works well for me.
Hope this helps you.
