Best advice! Problem with most divers having dry throat is quick breathing.. too much dry air passing thru ur throat not giving enough chance for your body to naturally produce moisture.
kind of agree with this..
the lining of the throat kind of naturally produces some kind of liquid-mucus that is normal
[our bodies produces all kinds of these to protect us actually - eyes, inner ears, etc]
when this get damaged or dry out (in this case the compressed air), we get this tickly feeling aka dry throat
