I had cancer on the base of my tongue. I had chemo and radiation, so my case may be different than yours. I just looked at my notes and it was 15 months after the end of treatment when all food tasted good. I remember that my taste for sweet things was the first to go and the last to return. Later in my recovery I was more interested in savory dishes like Teriyaki Chicken from Panda Express and BBQ from a local steakhouse. At that time I also started watching Pati's Mexican Table on TV. She is always happy and excited and good at describing food and making it sound delicious. I even went online for her recipes and tried to cook some of her dishes. Imagine what would taste good and try to find it or make it. You mentioned that your taste buds seem altered, so you may need to alter your diet and try some new things. If you can't think of anything or don't feel like cooking, maybe go check out a buffet restaurant and sample everything!
