I'm a nervous wreck right now and I'm nauseous beyond belief. I love how I worry so much about throwing up, then I start feeling nauseous. Does anybody have any advice for me as far as staying calm? I'm so afraid of having a panic attack, throwing up from the flight (even though I've flown 5 times on a plane before and never got sick), catching a stomach bug, or eating something bad in Puerto Rico. Any advice please? Pretty please?
