One of the legendary side effects of chemotherapy is... nausea. Oh, that glorious upheaval and queasiness that leaves you feeling crummy, woozy, uncomfortable, and all-around gross. They say that when you're nauseous, the best thing to do is the exact opposite of what you feel like doing: eat. Of course, most food is completely unappealing while nauseous because of taste, smell, texture, whatever. But ya gotta eat. So... soda crackers (or saltines, if you're so inclined) to the rescue.
