It was time for the “flooding the mask” skill. That was the one skill I was concerned about and not confident in. I somehow managed to partially flood my mask and quickly clear it all in one breath before I even had time to panic about water up my nose. But later on it was time to fully flood the mask and clear it. I couldn’t do it. I tried a few times but I would either get water through the regulator or up my nose, which would cause me to panic and immediately surface. I don’t know how to breathe continuously from the regulator underwater without getting water up my nose. I would have to hold my breath so that way the water doesn’t get inhaled.
