As few of you know, my brother is a neurologist. He is just not an MS doctor.

This is what he had to say:

I hadn't heard about it, so I looked it up = probably the same information that you have. It seems to me that it is not likely to be harmful, although it hasn't been studied as to either effectiveness or as to toxicity. You can't rely on inidividual reports. There have been many drugs over the years which are touted as effective for this or that, which then are proven to have no effectiveness. Think about almonds for cancer and all of those who went to Mexico to get some sort of almond extract therapy.

Are you aware of something I'm not? If Wingerchuck is an MS expert, he may be more in tune with reports about naltrexone.
