Road cyclist symptoms and conditions

I was started on Advair HFA about 35 days ago. A little background about me is that I'm 35 years old, in good physical shape. I'm a competitive cyclists doing road races anywhere from 45-100 miles, I work out 2-4 hours everyday. I've had lifelong chronic asthma, but have fought the disease with my healthy lifestyle. I also play the saxophone.

Since I've been on Advair I've developed a constant sore throat. Been coughing up stuff constantly when I'm out training on my bike. Can't seem to sleep for more than a few hours at a time. The worst side affect has been the leg cramps which are killing my training for up coming races. I have constant leg cramps that force me to get out of bed over and over to work them out. My energy levels have dropped to the point that I can't do even half a workout without being totally wiped out. This is coming from a guy that averages 60miles a day on the bike, the other day I couldn't even do 15 miles and had to stop from the constant cramps and tiredness. This stuff is a nightmare. I've gone back to using nothing but my albuterol inhaler. I'll continue to do lung exercises 4 times a day and completely clean up my diet and basically get this stuff out of my system. Let this be a warning that you can't get something positive without something negative as well.

I was diagnosed with low thyroid in July of 05 after my MD ran some blood work due to a rash and fever. Prior to that, I had no symptoms of hypothyroidism and in fact am a competitive triathlete and road cyclist. MD put me on Levothyroxine and even though my levels came down, I noticed no changes in energy, metabolism, etc. In October, I began having extreme headaches accompanied with numbness and tingling. MD refered me to a neurologist and after numerous, expensive tests, everything came back negative. Blamed it on anxiety and stress. I blame it on this drug. I feel worse now while my levels are normal?, then I did when they were originally diagnosed as being too high. What's the benefits of this drug if it makes you feel like crap? How can so many of us have these same side effects with not response from our doctors?
