Sorry to hear that you're still having trouble eating. I was lucky in comparison and can eat almost anything once again, although I occasionally have trouble swallowing and I eat slower than I did before the surgery.

I use a masticating juicer to juice vegetables and supplement my diet that way. It was something I bought even before I was diagnosed & eventually had my subtotal glossectomy, because I needed to find a way to add more vegetables to my diet. Drinking a nice green juice occasionally, makes me feel a lot better. I am not one to advocate using this for a full on diet change or to go on a juice cleanse, but I have found it helpful to improve my diet.
