Im looking into this. Lately I have made a lot of glaring errors that have led me to ask my partner to double check all my travel itinerary's. I've had some difficulty not only with memory but with processing information. Its only mild and most of the time Im OK buts its something that's creeping up on me and at 52 its probably the right age

However Im even more interested if its something that may help with Pn Pain.
Mrs D your issues are ,mostly muscular and arthritis based, or are you seeing improvement in nerve pain as well

I deal with I herb and they have it there. Looks inexpensive
