San Francisco - here I come!

I've lived abroad and spent several holidays in France(Paris, Quimper, Loire Valley, Antibes), Spain (Santiago de Compostela, Barcelona, Sitges) Italy (Bologna, Rome and Naples) and Denmark (Copenhagen) - but I've never been outside of Europe. That's going to change in March and April next year, because my other half and I are planning to spend ten days in San Francisco.

I am really looking forward to it, but I am hoping for a smooth flight. I don't mind flying, but turbulence scares me. I refuse to drink alcohol to 'zonk me out' during a flight, so I'm scoping out ideas about what to take or do to take the edge off my anxiety during our ten hours in the air! I may leave my heart in San Franciso, but I don't want to leave my lunch on the floor of the 747.
