question: Hi there, I'm very excited for something that's happening tomorrow.  It only happens a couple times a year and I always get extremely excited for it.  But here's what happens in the hours before the event; I get so excited that my nerves go crazy.  I get butterflies in my stomach so bad that I feel nauseous, and I get very shaky and twitchy, especially in my legs.  I never throw up, though.  Do you have any idea how I can get my body to calm down?
