9. Wolfsbane Potion was created after Remus' time in school and therefore unavailable to him. Even if he knew he would be unable to perfect one as it is a complicated potion that most qualified wizards are incapable of making.
"Effects: While this potion doesn't cure lycanthropy, it does prevent the extremely dangerous dementia which would otherwise accompany the transformation from human into werewolf."
--"Werewolves take it to alleviate their monthly symptoms (painful transforming and aggressive behaviour). Although it isn't a cure for Lycanthropy, it is a great advancement in potion-making and is one step further toward a cure. It must be taken for the full week before a full moon to have any effect, and sugar makes it useless. The potion was invented by a wizard named Damocles, who received the Order of Merlin and is the uncle of a current Hogwarts student, Marcus Belby."
10. As the full moon draws closer a werewolf will often feel ill.
