Hey katie,
Regarding your taste - this was one of my biggest concerns when I found out about the treatment I would have to do; I may be small but I am a big eater

Luckiy, my taste is back nearly 100% now, and I am able to enjoy all of the foods I enjoyed before. It takes me longer to eat, but i pretty much don't have anything i cant eat, other than spicy food (and sometimes giant sandwiches)!
A peice of advice though - don't eat your favorite foods past like the first week of radiation, stick to blander foods. sushi is my favorite food, and i tried to eat it once during radiation and almost threw up. i just recently started to like it again within the last few months.
