My husband did take a full course of Ethyol (35) and that may have helped his saliva, but of course it's impossible to know where he would be without having taken it. As for the differences between Salagen and Evoxac, one thing I have read online is that Evoxac seems to last longer for some people, so it can be a help especially at night for people who are being awakened by dry mouth.
