Chris,
I had IMRT both sides (35 sessions) and chemo weekly. My taste also started to return, albeit in fits and starts, at about 4 months out. More importantly, my salivary function began to kick in around 6 months which made all the difference for me in regard to eating with any enjoyment. Prior to that time, water was about the only thing I found to facilitate eating. Dairy products increased my mucous secretions (and still do)so I don't drink a lot of milk. I'm now 33 months out from treatment and enjoying "most" any foods. Hang in there!
