What can I do to ease my nerves without alcohol?

I'm nervous about seeing my long distance boyfriend which I know is weird because we talk all the time and have seen each other before and have been friends for a long time but now that we are more than friends, I feel nervous everytime we do meet up. Once we drink, I feel warmed up to him but we are going on a date and I don't want to drink before hand just to calm my nerves down. What can I do to ease my nerves?
