I HAVE JUST BEEN INTRODUCED TO MY FIRST POOL SESSION AND I AM HAVING PROBLEMS WHEN I HAVE TO TAKE MY MASK OFF UNDER WATER AND ONLY BREATH WITH THE REGULATOR. I KEEP INHALING WATER THROUGH MY NOSE AND DON'T HAVE ANY IDEA OF HOW TO CONTROL MY BREATHING THROUGH MY NOSE. I NEED TO KNOW IF ANY ONE HAS ANY IDEAS OF HOW TO PREVENT WATER FROM ENTERING OR AN EXERCISE THAT COULD BE DONE TO HELP ELIMINATE MY PROBLEM OTHER THAN HOLDING MY NOSE SHUT WITH A NOSE CLIP. ANY SUGGESTIONS WOULD BE HELPFUL. THANKS..
