If I am fortunate as you indicated it is because I worked to eat right and keep my level of fitness up for the past forty years. I'm not saying you are, but many do what they want without concern for what develops later on and then want a pill to cure the problem. I am truly sorry about the situation you are now in, but I still believe when a doctor does not tell you what you want to hear it is time to explore another doctor. Only then will you know what your path out of the problem really is.
