So, is a cup of OO necessary if many chuck it up?

Congrats on your flush.

I am wondering (as in my subject line) whether a cup of OO (Olive-Oil) is necessary, since it doesn't seem to go through every's stomach and yet stones are produced.

Perhaps HALF a cup would be enough, since this would pass through the stomach and then not be upchucked in the morning.

Thoughts?

Thanks.
