Retain oil overnight?

I noticed more than one description of the Classic Coke Flush. One here just says drink the mix before sleep, the other (Sutter post) says the oil will pass within a few hours:

Immediately lay down on your right side, knees slightly bent, head properly supported, for 30 minutes. Then 15 minutes on your left side and 15 minutes on your back. Then get up and move around a bit. Nothing strenuous.

Results: The oil usually passes within a few hours.

Which one is the correct way? Also the 1st one says to take magnesium citrate in the AM.
