I de-stress by driving with the music up......LOUD!! Of course, it must be by myself - adding children adds stress LOL
I actually just made a playlist on my iPhone titled "Stress Relief" with a bunch of loud, fast tempo music. I popped in my earphones this afternoon for a quick moment of relaxation. Oddly enough, quiet or soothing music just makes me feel frustrated and jittery when I'm stressed. I love Nickleback's "Burn It To The Ground" when I'm stressed and angry.
If I'm stressed and tired, though, I like a hot bath. And a glass of good wine. No certain order, together is even better.
