PredniSONE and eye doc

I had a kidney transplant feb08. I was put on prednisone as a rejection med. So far, i have gained 50 lbs, my hair has fallen out, had mood swings when first put on it. Haven't noticed them lately, have little bumps under my skin, not acne, have started noticing slight breathing problems, when trying to walk to lose the weight. Yesterday I was diagnosed with cataract. Eye doctor said that it is another side effect of the med. I am under the impression that, I am on this for rest of my life. Whats next?
