I'm planning to get scuba certified fairly soon, but there's one issue that I'm aware of; if I can't breathe through my nose, I feel like I'm going to smother. It's not a physical issue, I won't actually suffocate, it just drives me nuts. Even a stuffed-up nose makes me feel like I'm going to suffocate the entire time... Drives me insane.
About five years ago, I did this thing at the Monterey Bay Aquarium, where you get to wear an air tank and go swim in this massive tidal pool to see crabs and stuff. Everybody stayed right up at the surface, no real diving, and it was AWESOME, but half the time I felt like I was gonna smother.
Are there any masks that let you breathe through your nose as well as your mouth? I'm pretty sure I've seen pictures of masks like that...
