Hi there, evoxac worked great for me; I took it for 1 yr 3 mos after treatment ended. So I just stopped last month. Don't give up yet, okay? My mouth is almost completely back to normal--a teeny bit drier now and then, but not usually. And I can eat almost all spicy foods again, too. If you're not using evoxac, please ask your doctor for an rx. Really made a HUGE difference for me!
Good luck!
