DuffyPoo:
I think what ciraarana meant was that Fake Crouch had to remember to take the potion every hour: "But I think, in the excitement of tonight, our fake Moody might have forgotten to take it as frequently as he should have done ... on the hour ... every hour ... we shall see." GoF Can Ed pg 592.

Yepp, that's what I meant. You have to drink some every 59 minutes or so to stay the other person. And in DH, they don't and still don't transform back.

Although, perhaps, it's because they took a "large dose". Perhaps the more you drink the longer it lasts. But if that's the explanation, I would have liked to be told so.
