So I've been medicated for about 4 months now and I feel great

Not in a manic way, but I just feel "normal" I guess. My moods are almost completely stable and I really only get manic if I miss a dose of my meds, drink, or both. (So I obv tend to avoid those situations.)
Anyway, I've been sleeping A LOT. Like 12-14 hour nights, with random naps during the day. And the weird thing is, my meds are mildly stimulating (plus I take adderall for my ADHD) so I don't really "sleep" when I go lay down to take naps. I just kind of lay there because it's comfortable and I'm bored and don't know what else to do with myself. (I'm not working right now either, my days definitely lack structure).
I can't tell if I'm depressed or not... all I know is that I'd rather sleep (or at least try to) than do most things. If I get even the slightest bit anxious, tired, bored, or whatever... I'll crawl into bed and close my eyes. I say it's kind of like my "meditation" time, because I don't really sleep when I go lay down, it's more of something I do for comfort, not because I'm actually tired. Does this make sense? Does anyone else sleep this much? Do you feel it's because you're depressed or just bored, or something else? Thanks!
