I'm Confused About Some Aspects of Coffee Enemas

I'm confused about coffee enemas. Some people say lay on the left side while retaining, and others say the right side....Which is best and why? I also had my gallbladder removed but feel EXTREMELY toxic and currently unable to work because of chronic fatigue and many stomach and memory problems. Also, some say to do a cleansing enema afterward to remove the toxins dumped by the liver.

I tried a 3 cup coffee enema this afternoon. I only did one and have tried before but couldn't retain for very long. This time I was successful at 15 minutes. I only did one. Soon afterward, I broke out with several rashes and swelling all over my body and turned red like a sunburn with itchings. These eventually went away. Anyone have any ideas as to what is happening and how to be more effective? Should it have been followed by a second one or a cleansing enema?
