hi, the doc wanted me to take Ensure, and I think this is sensible. I am underweight and not doing well. However, I cannot have any soy, excitotoxins, potato, artificial sweeteners, or flax, oats, or other higher-fiber things (and more stuff, but this seems to be what I am finding in nutrient drinks: maltodextrin would be excitotoxin and could be potato). I used to take whey powder but then I realized it was giving me tinnitus (though not as badly as the amino acid liver detox formula I tried once). It's possible tinnitus would be preferable to being underweight? I am not sure about that. I do not know what to do. Does anybody have any suggestions?
