I buy cilantro and freeze in freezer bags. Usually a half stalk in each. Take one bag, put in blender with a small carton of Yoplait yogurt, add orange juice and liquefy into a smoothie. Makes enough for 2 glasses. I take one glass per day. Was on the wagon for a year but it’s come back a little so I’m back to smoothies. The yogurt and OJ make for a good drink. And my Grovers goes away.

Have you tried Flanax, it's capsacian (hot chili pepper). Sounds crazy, but the brief burn felt better then the itch. My derm recommended. It burns when first applied briefly for a few minutes, but then it suppresses the itch enough to fall asleep. The relief only lasts about 30 minutes, but it was a godsend for me when symptomatic. Wear gloves to apply, don't get into eyes or around your mouth. Yet I don't know if it helps with neuropathy, but it helped with itch with GD.
