I don't know anything about the dry toast, maybe a precaution that one should eat something, but not something that might make one nauseated. having said that speculation, there were no restrictions given to Lucie, my wife, as she has gone through chemo. We always bring something to snack on, and even bring a lunch if it is going past noon. Lucie's chemo normally takes about 4 hours, so we go prepared for that time. I have found the kitchen there so I usually make her some hot tea or iced tea, and get coffee for myself. Lucie has never been sick during the chemo treatment, but about 4 days later, it hits. Don
