Danny,
My husband couldn't tolerate apple sauce either and perhaps the ice cream is too cold. Think of bland, barely warm or room temperature stuff. He even has to let the milk shake warm up a little before he can drink it. He also found that sugared iced tea (not too strong, not too cold) was easier to drink than water. He eats the tapioca pudding at room temperature (it's the kind you buy in little cups that don't need refrigeration.) He found vanilla flavor is easier than chocolate or other flavors. I know this is a very difficult time, but you will get through it. Don't push yourself, but be persistent. Perhaps take a slightly longer view of things and realize that healing won't take place overnight. But it will happen. Best of luck.
