--and caustic personal cleaning products.

I have to be very careful what soaps I use--I've always had dry skin, especially in winter, when one is going from cold dry air into warm dry air quite often. I do humidfy the lving quarters, but I've also found that using harsh soaps, like Ivory, can really dry me out (so I don't anymore). And, I find using the fish oils definitely helps.

As to the other stuff--yes, sweating difficulties/abnormalities, heart misfirings, and sluggish digestion certainly fall into the category of possible autonomic effects of small-fiber neuropathies, though there are lots of possible causes of all of these that are not necessarily neuropathy related. Those systems tend to be a little more sluggish with age--especially the digestive tract, if it's getting too many simple carbs and not enough fiber/protein. The question would be how quickly have these effects come on, are they concommitant with your other neuropathy symptoms, and are they rapidly progressing, or only very slowly, and how disruptive are they becoming. Mild sweating difficulties or occassional missed heartbeats, or speedy heatbeats, are not generally dangerous, but if they occur constantly, or are severe, more attention needs to be paid, Similarly, sluggish digestive/eliminative tracts are extremely common, and often are related to medications, and are often easily controllable with supplements, warm beverages, or exercise, but if they progess to extreme dimensions (kmeb can speak all about that), that's a much more serious situation.
