I think you’d have to talk with your doctor about the feeding tube and ask. They might be able to put something temporary in. I lost quite a bit of weight as well, but I know that eating frequently through the day can be helpful to some. I was going to try this one product called Huel, to see if I could stomach that. It seems to have a bunch of essential vitamins and natural foods in it. I think it’s also vegan too, if that helps. Have you tried making a smoothie with oats and veggies in them? Just trying to think of everything possible.
