Gary, thanks for answering back. I also had right side tonsil cancer which was removed surgically in November. Then I had radiation beginning Jan 9 for 6 weeks. Just curious, did you have any problem at all with phlegm? During radiation, I went thru major hell with heavy phlegm. Now, I have only a small bit every now and then, but during radiation I was gagging constantly due to the phlegm. Some people have the problem and some do not. Also, my voice gets very hoarse some days, perhaps from overuse, really do not know why. I constantly lubricate carrying a water bottle, however, some days my voice is very weak.I have come a long way, however, i do have my setbacks occasionally which throw me flat for a day or 2.
