I don't know if this will be helpful, but try taking the olive oil with an equal amount of coca-cola classic (also use the grapefruit juice). I know coke is not good for you if you drink it regularly, but it makes the oil go down MUCH more easily, it cuts down on nausea, and it must have some action on the liver because my flushes with coke have been much more succesful than the ones without; all other things being equal.
