I've decided that the production of an artificial sleep-production spell is necessary before I move on to any other manner of study, magical or otherwise. Of course I have to figure out exactly what it is that occurs during sleep before I even begin devising a spell that replicates the effects of it. And as court jester, it would be unseemly to walk about the castle questioning everypony I come across as to the various symptoms and causes of a good night's rest. Oh what to do. . .
Addendum: I remember the king mentioning something about alchemists my first few nights here. He brought them up as a solution to the very insomnia that plagues me now. Perhaps I might be able to learn something from them. I should probably ask around and see where they live. The king would probably be a good place to start.
