Coffee retention enemas are generally used for detoxification, mainly of the liver and gall bladder. It is not used for general cleansing. With the info you provided I can only suggest a few improvements for your situation.
First, before taking the coffee enema, you need to empty your bowels and then take the coffee retention enema.
Second, after expulsion of the enema rest for awhile and don't be actively moving a lot. Just rest say half an hour.
Third, read my blog, titled "My challenge", link below.
If you have any further question ask and I will try to answer them.
