Marineboy65:But worse than that, I had never experienced dry mouth until 10 minutes into my first dive with this reg. It's not just a slight case of dry mouth, it's absolutely chronic!. After 2 dives, in one day, with this reg, i was peeing orange for 2 days, drinking as much water as humanly possible took 2 days to totally rehydrate. I'd hate to think what would happen if i was to do a liveaboard with this reg. Doing 3 to 4 dives a day, for 3 or 4 days or more. I'm sure i would end up so dehydrated that I'd undoubtedly end up with the bends.
I doubt if the dry mouth you experienced was caused by the regulator. Except for a couple of regulators that injected moisture into the air, all regulators provide the same amount of dryness. Dry is good because the only source of wetness is sea water and you don't want that inside your regulator.
Sherwood Magnums were known to be "wet breathers" leaking sea water with every breath. Maybe you got used to that and felt that the Aqualung was dry by comparison. But, when it comes to regulators, most people believe that dry is good, wet is bad...
Hydration is a whole different issue. We recommend to all our divers that they consume several bottles of water during a days diving. You lose water through the dry-air (from the tank, not the reg), from sweating (yes, even underwater) and from the sun.
