Even when fully hydrated (warming my wetsuit every 15 minutes) my throat and mouth do get dry. I usually end up having a coughing fit. I've been told the only way to correct this is to switch to a rebreather.
I get the same thing.
There's a product out there called the "biofilter" which may help, but YMMV. I've never personally used it(I just swish some salt water around and spit it out).
