I am not a doctor but i can tell you everybody is different. I have not ever had an enema but i was watching the Spa of Embarassing Illnesses and they do coffee enemas nearly every day on that show. Not every one on there could take the whole enema at first, i think it was a litre. Tho things did improve after a few goes as the system became clearer and lots of rubbish was removed from the colon. If you feel this is the right thing for you to be doing then stick with it and just keep asking that nurse for advice and support. Don't worry about
amounts, your body will tell you what it needs and what it can handle at the moment. If there is anyBODY in this world you should trust, it's you.
Good luck lion00
