Desperately in Need of Raw Snack Ideas

The busier I get at my job and with my classes, the more often I will have to deal with eating outside of the house. It's such a challenge! My desire to stick to raw foods is so strong that at times I will risk severe stomach pain, headaches and lightheadedness because I stubbornly refuse to eat the non-raw foods available- I just drink water and go hungry. I have to figure out how to deal with this. Sometimes I am lucky and there is salad or a fruit tray available at the venue, but often there are just fattening entrees and foods I don't eat anymore. Catered events often have vegetarian options, but many of them are swimming in cheese or oils. If I liked carrots and celery I would carry those, but I can't stand them and they don't fill me up. Apples give me a stomach ache, and other fruits are too soft or too messy. Perhaps I should carry flax seed crackers and eat those during the lunch breaks we get during these marathon workshops, seminars and staff meetings. If anyone has better ideas, though, I would appreciate your sending them.
