I feel you!
I used think that I was addicted to sleep, and that I loved it too much. But then I got tested and found out that I have narcolepsy. You might have it too? It's actually pretty common, it's just very under diagnosed because most people don't know about it.
The little light box you were talking about. I also have one of those. Sometimes I use it to get up in the morning. But most of the time I use it to counteract the affects of SAD. Mine is called a happy light. I would recommend it. It really does help wake you up and somehow actually makes you happier.
