Hi
I'm a bit confused that someone would suggest HCL to help with a flush, because, if my memory serves me well, HCL is principally there to provide the acidity necessary for the enzymes that digest protein. Fat is mostly digested in the small intestine by bile, so HCL is unlikely to have any real effect on the oil in a flush and would probably just serve to irritate the stomach.
Anyway, you don't need it to flush - good luck
