No, I have not really searched for treatments. For a time it seemed as if doctors took autonomic neuropathy as not real. My symptoms involve the GI tract, urinary, intestinal, all of which can be a part of aging and since I'm mid eighties I don't want numerous testing which would involve more pills that could interact with the ones I take for A.Fib and tackacardia and gastric reflux. I prefer to live with what comes but periodic episodes of fatigue lasting for several days are the hardest to deal with. I've been told it's part of A.N. but I would like to know if others deal with this. Often me BP will be very low when the fatigue appears and light headedness, pre syncope come with it. I think I will feel more relieved if I find it is truly part of AN.
