This happens all of the time. I feel like I am just wanting to take a deep breath so bad, but cannot. It is rare that I can get a deep one in. What is this? Is this common for FM? It is driving me crazy. Stressed or not, it is almost constant. I want air! Don't get me wrong, it is not like I am hyperventalating or have asthma or anything. Just this constant need for air!! Anyone know anything about this?
