pinklady that must be awful for you and really affect the quality of your life, I am so sorry.
Have you had tests done to make sure that the permanent diarrhoea is due to neuropathy and not something else, tell what are your bg readings, whats your recent Hb1ac? With neuropathy is is very, very important to keep your bg as near as possible to that of a non-diabetic and for quite some time too and the affected nerves will start to heal again.
What is your diet like and which medications do you take? If you have had this condition for 10 months now you might also be lacking in certain vitamins and minerals because the food is passing through too quickly? Please discuss this with your doctor or nurse, dont rush out there stocking up on a whole lot of supplements.
So a search on neuropathy, there is a link in this forum somewhere, just type the word into the search box on the top right hand corner.
I hope that you get better soon
