Thank you, limey.
Did you get an urge to defecate after you got up? I usually lie down for at least an hour after enemas, planning about the same for FMT too. And almost always after I get up, I have to make a trip to the restroom to out whatever was left inside..
The specialist at the Hospital that I go to for my FMT say that after 20 mins the FMT will have done its job so even after that if you lose some thats fine,
