Hi Dave,
Just a quick addendum to MrsD's note here on magnesium.
My feet ar both toasty warm this AM in a very air conditioned room!
I have recently had trouble with vasospasms in my feet and in my left hand (after a small surgery on my left arm--nerve issues).
I have noticed how warm my feet are this AM and were all night!
My left hand looks better and operates better, too!
This is after two doses of an inonic fizz magnesium.
I cannot say if this will be helpful to you. I did want to share this with you, however.

Again, welcome!
