I was put on Cyclophosphamide for 7 months and although my sense of smell and taste returned I personally do not think it had much of an effect on the Churgs as I had a flare a few months after finishing.
I put on a lot of weight due to the Chemo and steroids so I joined Slimming World and lost 1.5 stones
I had my meds changed from Cellcept to Mycophenolate and this is working although I was re admitted to hospital with breathing difficulties.
