When they are higher level spells, absolutely! If what you are using is fae magic, I imagine it would feel very draining at first!

[The most recent memory of it had been healing Leo, but that's not the happiest memory for either of them, even now, so they'll politely duck around that one.]

Practically all of the spells I use for the parties I've put on are fairly low level illusions, so most of the spells you've seen me cast wouldn't drain me in such a way. But I have some more advanced magic in my back pocket to use when necessary, and I'm sure, without regular casting, it would tire me out too.
