morning sickness help

Mandy
How do you handle morning sickness in public? I seriously have to throw up 15 minutes after eating anything and I feel gross and judged about throwing up in public toilets. On average I'm loosing a 1/2 pound a day because I can't keep anything down so I can't just not eat. I do have an appointment next week to talk to my ob but I want some ideas on how to cope until then.
