Given my own experience, and from what I hear from many patients, you are very normal in your recovery. I have posted here before saying that most people can count on one month of recovery for every week of radiation. I was 10 months out of radiation before I was eating enough to consider having my PEG tube out. I was over a year out before my taste stabilized, with different things returning at different times. (First salty, then bitter, then sour, finally sweet. Sweet never returned completely and chocolate, that I used to love tastes like lard now). It sounds like you are experiencing the normal course of recovery.
