<< Can anyone tell me when and how often Lupin has to take Wolfsbane?
 Is it something he has to take on a daily basis or just when a full
moon approaches?  I had an idea that he had to take it for a
fortnight running up to the full moon, but I'm not sure where I got
that from and whether it's correct. >>

PoA page 258 UK paperback: Lupin says: "The potion that Professor
Snape has been making for me is a very recent discovery. It makes me
safe, you see. As long as I take it in the week preceding the Full
Moon, I keep my mind when I transform .... I am able to curl up in my
office, a harmless wolf, and wait for the moon to wane again."

I understood that to mean that he has to take it once anytime during
that week, and other people have understood it to mean that he has to
take it daily for that week. Why does 'in the week preceding the full
moon' imply daily for seven days more than it implies three times a
day for seven days? Anyway, I don't see how anyone could understand it
to mean daily all month 'round, or daily for a fortnight.

useless." It must be canon because I knew I had read it somewhere. >>

This is the first I've heard of Remus.Lupin.net and it is not really
good advertising for it that the first I hear of it is that it spreads
misinformation. However, I'd like to visit it since I'm a BIG fan of
Remus Lupin, and my browser says "remus.lupin.net not found".
