3. Lightly blow on your thumb nail. It sounds weird, but it works.
4. Breath slowly with your tongue in the middle of your mouth. Don't let it touch the roof of your mouth or your teeth.
5. Close your eyes and picture your happy place. It could be your bed, with your puppy, or anything that makes you happy.
