Once I'm underwater, I don't deal with breathing, but I put even more emphasis on breathing before immersion. This time I tried pure oxygen. At first I didn't take it seriously, but after my first experience I changed my mind. Now I know that there is a great potential hidden in oxygen. I find the combination of hyperventilation and oxygen breathing especially wonderful. I recommend it. You have to try it.
