My favorite tea to drink when I need to relax is Yogi Calming Tea.  You can find it at Jimbos or any regular grocery store that has a healthfood aisle.  It is about $4, but well worth it!   It is full of really great ingredients and smells like lavender.  I give it to all of my girlfriends when they need to have a little down time.  My favorite thing about the tea is the saying on each teabag. Namaste.......
