If you read Dr.Clark, she's not afraid of enemas and will recommend a few a night in a row. So on that theory, I'm sure your fine.
I personally did coffee enemas the week leading up to the liver cleanse. Durning the enamas, sometimes I would get the same exact "filmy" stuff I would get on the liver flush. Then when I did the liver flush, it was either or failure, or the coffee enema cleansed the liver some.
