Hello Tom. I'm about 8 weeks out of radiation and this week I have finally noticed some overall improvement. I went from having way too much ropey thick salvia to having very little sticky salvia. Now with all the extra out I'm able to take really few bites of food. I have to let the food sit in my mouth and get soggy and then I can chew. It's kind of like I have to let my mouth know what's coming, what's in there and give my mouth time to get adjusted each bite.
You'll get there and a lot of people I've spoken with got at least some of their salvia back. I've also read a few clinical studies where a majority of the people studied got quite a bit of their salvia back.
