We copped some serious turbulence yesterday for at least 4 out of the 6 hours that we flew. I started to feel pretty ordinary about an hour and a half out of our destination so I got into a bacon and egg toastie. Took twice as long to eat while getting thrown around but it eased my stomach. You don't want to eat or even think about food when you're feeling like this and it might not work for everyone, but try getting something decent in your stomach could settle it enough to get your mind back on the job.
