Hi, actually I really like cycling, but as am asthmatic, I was having breathing problems with the lack of oxygen..lack of blood circulation, and since then, I took on VENTOLIN ( you can find about it COMPLETELY on the following link):

And guess wot: it's utterly helpful. As a drug, it worked miracles for me, and I had no necessity to quit cycling. Thanks, Ventolin. And good luck you all!
