Mile rides symptoms and conditions

I have been using Advair 250/50 for about 4 or 5 months to control my exercise induced asthma primarily when cycling on my 50-60 mile rides. So far I am pretty happy with how it is working, although I have noted that others have had initial success only to have some serious problems later on. My only complaint is the hoarseness, coughing and dry throat it gives me. I now have that somewhat under control with some aggressive cleaning of my mouth with water after I take a dose. I swallow some water and swish it around my mouth very aggressively, spit it out and then make sure I drink 4 or 5 gulps of water to clean my throat with the emphasis on gulp. Now the hoarseness and coughing is relatively minor. I also take two puffs of Albuterol about 20 minutes before riding. This is pretty standard for those that do vigorous prolonged exercise.
