from my experience I would say sleep and being in bed most of the time after the OO (Olive-Oil) drink is VERY important.
You say, you have to run to the bathroom during the night. Did you try an enema 15 minutes BEFORE drinking the OO (Olive-Oil) mix? Enemas at this time induced many bowel movements in me. Maybe this approach will give you a good night rest.
Most important of all IMHO is stay totally relaxed and without any unnecessary movements for at least one hour after the OO (Olive-Oil) drink. This is the time the liver does most of the job and should not be disturbed.
