Len,
I had to chime in here because we all have different experiences and recovery times. My mouth sores, like in the back of my mouth (with were actually ulcerations caused by radiation damage) took a long time to heal completely. I also had thrush which dramatically impacted the radiation damage healing process. Have they checked for that? Carbonation, spicey or acidic foods will burn like hell with thrush.

I also had blisters along the sides of my tongue but they were pretty much healed up completely by about 3-4 mouths. I can eat anything now, salsa, schezuan, hot chile, anything carbonated, etc. Not all of us suffer from a "restricted diet". At 3 months I was eating solid food.

I did choke a lot in the beginning but things have steadily improved (along with my salivary function). And also adjustments in my eating process.

I attribute this to 3 reasons:
1. IMRT
2. No surgery
3. No PEG
