A hot shower is often the best I can do but a good cardio workout helps as well.
I like to get out and go for a walk.
Go for a walk, call up a friend, grab a good book, put on some fast music and dance around the house, clean....
take a hot bath, listen to music, grab a good book, go for a drive, call up a friend, go for a walk
Bubble bath, read, listen to music.
