@hotfooted shared some information in a private message with me that may be useful for folks that have itching with their neuropathy and are taking gabapentin and magnesium. Excerpt from following page -- "Gabapentin works in the brain to prevent seizures and relieve pain for certain ... If you take an antacid that contains aluminum or magnesium, wait at least 2 hours ... Call your doctor right away if you have a rash, itching, trouble breathing, ..."

From @hotfooted - "just saw my old post about the itching and why I stopped taking Gabapentin and Magnesium… I recently started taking Gabapentin again and the newest directions state Not to take them within 2 hours of each other.. I had forgotten the reason why I stopped taking Gabapentin previously and my doctor didn't have that bit of information either.. Now I take them at least 2 hours apart and am having no problem so far! Thought I should get that bit of information out there in case someone else is having the same problem…"

Great tip since a lot of folks with neuropathy take gabapentin.
