text: one more for the scuba divers! how can i keep from getting "reg mouth" after diving? compressed air is sooo dry that by the time i'm done diving--whether it's one dive or four--i have reg mouth... dry, yucky, i feel constantly thirsty. for example, all i did yesterday was pool dive to work on some skills, yet i still feel like my mouth is all dried up like a prune. any suggestions on how to combat "reg mouth"?  thanks! :) there's not a lot you can do about it. diving dehydrates the body which, in turn, causes that dry, yucky taste after you dive. the only thing i can recommend; chewing gum. especially sour apple gum. it will cause you to salivate and gets rid of the taste. and drink plenty of water!!!
