Sleep asthma attacks

For a year, I have used CPAP (continuous positive air pressure) sleep equipment, waking and gasping for air after two to three hours of sleep.  This month I tried using the rescue inhaler when I woke for one night.  Surprise, I could sleep more than four hours!  Now I use two puffs of Albuterol from the rescue inhaler before I put the sleep mask on, as well as the one puff of Asmanex.  I can sleep over four hours most nights before waking.  Whew!
