I heard about an NIH Clinical Trial to increase saliva flow for people who have been a survivor for 5yrs+ and have some saliva after RT. It starts in August, requires daily visits for slightly painful injections for at least a 2 week period. Is this something I should consider? It is far enough away that I would need to stay there. And, it's for 18 days, then several checks over the next year. A Big commitment! No question, my saliva flow has been greatly reduced from RT, but over the 11 yrs it has gotten better. Some mornings I wake up and surprise myself that I didn't take a sip from my Camelbak (a non-spill water bottle, which sits behind my head in bed, so I don't need push my head up with my hand, sit up, and take a sip from a cup that I may spill....one of my little coping secrets!)
