If you are at all worried about blood sugar, you can buy an inexpensive meter at any drug store or discount store, and learn for yourself how your body is reacting to different foods. I have problems that can only be seen by home monitoring and on the oral glucose tolerance test. I respond horribly to sugar and refined carbs.

When I went low carb, my screening numbers drifted higher. As someone else mentioned, that's not uncommon as the body isn't in "panic-mode" trying to keep blood sugar as low as possible in anticipation of bad spikes.

If you think you're responding badly to sugar, then listen to your body. One thing is for sure...high glucose is an insult to nerves. Whether it's the cause your neuropathy or not, if you're spiking high, you're not helping your cause.
