Jody,
Do you have a feeding tube to fall back on. My husband was determined not to have one but is very thankful he did!! It is five weeks post treatment and he takes almost everything by tube still. Food totally nauseated him but the last 2 weeks he has started very cautiously trying little bites. Try for a lot more calories. He has lost 35 pounds, 25 since radiation and chemo stsrted. Even with taking in over 2500 calories he still dropped 2 pounds last week. Luckily even though food nauseates him he was able to keep the tube feeding down most of the time. Only had trouble when the gagging from the gunk in his throat would eventually cause him to get sick. Hang in there. It will get better, we have finally reached the place last week where things are improving.
