You are correct in that JR is T2 and does not claim to write for T1s. However, as others have already pointed out, the problems of raised bg and neuropathy are common to both types of diabetes, as is the question as to what bg levels are desirable. You might prefer to read Dr Bernstein, who of course is T1. This is from his book "Diabetes Solution" and is quoted on his site :
"DIABETIC NEUROPATHIES
Diabetic neuropathies seem to improve in two phases—a rapid partial improvement that may occur within weeks, followed by sustained very slow improvement that goes on for years if blood sugars continue to remain normal. This is most apparent with numbness or pain in the toes. Some people will even comment,“ I know right away if my blood sugar is high, because my toes feel numb again.” On the other hand, several patients with total numbness of their feet have complained of severe pain after several months of near-normal blood sugars. This continues for a number of months and eventually resolves as sensation returns. It is as if nerves generate pain signals while they heal or “sprout.” The experience may be very frightening and distressing if you haven’t been warned that it might occur."
