Advair, Singulair, & Xopenex here. I was diagnosed about 2 years ago after training and racing with asthma for the 5 years prior. I'd had the symptoms my whole life and just had never exercised hard enough for it to be a problem. Advair was a godsend until the seasons changed and the pollen brought all the symptoms back so my doctor added Singulair. I also recently switched to a Xopenex inhaler from Albuterol. Albuterol made me jittery and my heart rate would spike. Xopenex opens up the lungs without those side effects. The net result with all these meds is I can breathe on the low end of normal for someone my size & age.
