Yankee Candle. Unfortunately the scent has been discontinued, but this weekend I found several of them at T.J. Maxx! I was tempted to buy them all to stockpile them, but I stopped myself at two. I light it an hour before I go to sleep, and read my book while enjoying the soothing lavender smell. I swear that it helps me fall asleep, and the scent lingers for hours, leaving my entire bedroom smelling just heavenly. Maybe this post will convince Yankee Candle to bring this scent back!
P.S. For those of you who are allergic to scented candles, or simply don't like them, I suggest trying these battery-operated candles. Their flickering is quite realistic, and you can still get that "mood lighting" you're looking for. Plus, since there's no wax to actually burn, these candles will last forever!
