About 15 years ago I began having difficulty breathing when I was exercising. Gradually, my symptoms became more frequent until I would get out of breath just walking up stairs. I went to my doctor, and after an x-ray I was diagnosed with pulmonary sarcoidosis, an inflammatory condition that was leaving my lungs with a lot of scar tissue. My doctor prescribed a steroid inhaler and I took this twice daily for many years. Although this seemed to help the symptoms at first, over several years the inhaler became less effective, and I began to notice that my mind was not as clear as it used to be and my energy was decreasing. My doctor recommended that I increase the dosage of the steroid inhaler, but I didn't feel this was a good long-term solution. I had begun to lose my purpose in living.
