I got quite depressed by the same problem, seas, but as per some of the advice here, was able gradually to move towards foods. Taste (and smell) come back gradually. I do find smell is a big turn off - starting with cold foods is a good idea too.
Dunking biscuits is a good one - my favourite is nice soggy choccie bics! I still dunk now (3 years on), because my saliva will never return totally: so you learn to adapt as you go. Courgettes are the wonder vegetable to help stuff slip down if consistency is a problem.
But being patient is I'm afraid a necessity, it happens slowly. But it doesn't last forever.
