I like to drink a cup of tea. My preferred tea is one I make of Chamomile (Matricaria recutita or Anthemis nobilis--German and Roman respectively), Catnip (Nepeta cataria), and Peppermint (Mentha piperita). It helps calm the nervous system and relax the body. It's not recommended if you are pregnant though. Taking slow, deep belly breaths helps as well.
