True Believer, I have adult-onset asthma (I'm 64) and use two inhaler's each day a couple times a day. Inhalers only make your heart race if you use more than you are prescribed/need. Otherwise it makes you MUCH more comfortable so you don't have to be worried about shortness of breath.
Short and Cute. Sounds like you have Obstructive sleep apnea hypopnea syndrome (OSAHS):
