Arvind - Perhaps eating smaller meals and more often would help relieve the "pukish feeling". Always having water handy helped my son, too. He is almost one year post treatment now and still has to have water handy whenever he eats a meal and his meals usually include some kind of gravy or sauce to help food go down. The worst time for him were the 2-3 weeks post treatment and it was really difficult to get him to eat. He said that his throat felt like knives were sticking into it whenever he tried to swallow anything. I remember the day he actually managed to swallow 3 noodles with his chicken broth, it was a big celebration! It is difficult to have an appetite with sores in your mouth and throat or when you can't taste but it is important to take in some nutrition so that you don't lose too much weight or get dehydrated. My son did not have a PEG (feeding) tube but came really close too having to get one. Maybe you could ask your doctor about this if you feel she has lost too much weight. There are many good suggestions above so keep in touch. Things do get better!
