I don't know what the deal is, but every dive I do with the D1 2nd stage I get really bad cotton mouth. I thought the first time it was due to being a bit dehydrated, but this past weekend I did a lot of dives, no health issues, well-hydrated, and still had this happen.
My A700, S600, R395, and none of my Dive Rite regs make me feel this sensation. I don't get it. Two people I spoke to this weekend (one has Hog D1 and the other Apeks) have the same feeling.

I get the same thing. I think it parts my mouth too far apart to allow any saliva to form, I get really dry mouth that causes me to start coughing, gagging and I have to find ways to get my mouth wet again. I am in the process of finding another mouth pc to see it that helps me or not. I tried the menthol cough drop that I read about last dive, but I was using my Oceanic as my husband was using my Hog. I did not have the coughing fits, but that mouth pc is much smaller. His is going in for service.
