Good Point Ski: I didn't even think to mention that since it's so much a part of my life - I'm in Singulair for asthma. It's a maintenance medication and boy when I let the script run out - I can tell it within about 48 hrs. On the bad days: winter, high pollen count, humidity - I also use Albuterol 5-10 mins before I exercise to keep the airways open. That combination has worked for me now for close to 5 yrs? 6 yrs? I tried Advair but the steriods caused me to lose my voice and as a singer, I can't have that side effect, so the Singulair was less invasive and it isn't a steriod.
You might go to your doctor and see what course they can put you on that will help your breathing. It isn't the perfect solution, but you'll have good days where you feel like you're flying and they'll overshadow the bad days where that hill looks like Mt Everest and climbing it takes everything you've got!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
