Are you using plain water enemas or colonics to help with the constipation while doing the cleanse?...it helps a lot.
I wouldn't advise coffee enemas when you are constipated. coffee enemas do stimulate the bowel somewhat, but their primary purpose is to cleanse the liver by stimulating it to release toxins. It is quite powerful. If the bowels are not moving properly and you're backed-up the toxins from the liver are not able to exit the body fast enough and some of them will be re-absorbed when they're hanging out in the colon...only to re-circulate in your system and eventually land right back in the liver. When this happens you can feel pretty crummy. My advice is to hold off on the coffee enemas until some progress has been made with the Colon Cleanse and eliminations are more regular. They are more effective and comfortable that way. Just my opinion...
