Anymore, if I have a flare, it's usually because of something I've eaten. Have you considered giving up the nightshade veggies (tomatoes, potatoes, peppers, egg plant, paprika, tobacco, pimento)? Some people can't tolerate them with neuropathy--there are a number of posts about this. Sugar also does it for me so if you can give that up, you'll probably have less pain. Eating isn't as pleasurable as it once was, but I can make the adjustments.
