I wouldn't reccomend drinking orange juice your first time, but if you want to go for it. Do you know how many grams you'll be eating? Make sure you're in a comforatble environment where you won't be disturbed by parents/people you don't want to talk to. Don't drive! Just chill out, put on some cool music, etc. Make sure you have an experienced sitter with you incase something does go wrong, he won't be tripping and can make logical decisions.
