I wish I could be of more help, but the only time I really had any desires to not eat was when I was switching from the feeding tube back to oral eating. That was because I was on a continuous feed with the feeding tube and when I would try to take in the drinks by mouth, I would get super full super fast and feel awful after. It was pretty frustrating. But once I got over those issues I was all about food and am constantly eating (and still losing weight I might add).
