Yes my father follows something like the zone for his MS. I saw the doctor and she referred me to a neurologist, which I am not excited about because 1)they are going to do a lot more tests all over again, she says and 2)I don't have a good history with neurologists, they have personalities like doorknobs. But I am looking forward to some more ideas and solutions. She doesn't think the blood sugar is an issue, but maybe she is wrong. You have voiced my big fear. That being so young with such disruptive PN does not bode well for the future. I need to take better care of myself. Thank you for talking to me. You are the first nondoctor I've discussed this with. THanks mrsD.
