I only breath 7-8 times per minute and my blood oxygen level has been a little low lately. I tend to feel dizzy sometimes and weird. I have lost 20+ ponds and can do cardio for over and hr and not get tired at all. Blood pressure is great, pulse is 60 or lower normally.I have the sensation of not being able to take a full breath sometimes and the dr put me on albuterol. I do not think I have asthma, i can run for an hr and be not even slightest out of breath. am i crazy or is this normal?
