Not on any sort of regular basis. I used to light candles around here, but then I lost my lighter (guess it got thrown out and I didn't realize it), finally got a new lighter this year but I haven't used candles at all since then because I didn't know how my cat would react to them. Although maybe I'll light one right now since I've been reminded of them. It's an apple and acai berry scented candle, it ought to be good. :3
But other than that I've just been using "frosted pine"-scented Febreze at times as needed, and that's nice because I feel like it's not as overpowering as some scents. Or at least not as strong as the lavender vanilla scented bottle we had before then, whew.
Not sure what my favorite scents are, although I tend to prefer fruity ones. Taking a look at some of the other candles I have left: orange vanilla, caribbean escape (smells like pineapple/coconut), fresh linen...okay, one of these things is not like the other, apparently, but the linen scent is pretty good as well.
(Although if I could get one that smelled like oranges and cloves I would be all over that. I absolutely love that scent combo, it makes me nostalgic.)
