Charm,
well in that case I serve as the non PEG control together with Liz. As I wrote in another post alcohol is not = alcohol. It will depend on the % and how long and much you keep in your mouth. The effect (acetaldehyde production which is the carcinogen) is local and dependent on the local uptake by the cells (and their metabolism) and therefore in the contact time. So lower % alcohol seems better than higher %. With that logic (!) drink quickly then rinse your mouth with water.... (or use a PEG)
I am not aware of any hard data supporting the opinion above, it seems logical but that does not prove it.

In any case I personally am not worried about an occasional glass or two (wine) on the weekend.
