My father had a non-malignant tumor of the brain and after two surgeries he had no sense of taste or smell. Eating was very difficult but he learned he had to do it. The biggest part of learning to eat things you cannot taste or smell is in learning to imagine what it SHOULD taste like then putting that imagination to work as you get through your meal. When your tongue says it's cardboard you have to override that with, "Yum, this is great t-bone!".
He had one lasting after effect, every now and then he would be overcome, almost to the point of nausea, by either the smell of roses or fresh brewed coffee. Both were imaginary and he had no control over when these sensations would hit him. They're part of the "phantom syndrome" that many amputees go through. It's an interesting phenomenon, to say the least. I go through it being a mastectomy patient.
The best of luck to you and may you recover your tastebuds quickly.
