Well, it has been 3 days on this, and I thought I'd come on with my impressions so far:

1) I don't see any new energy yet at 5 gms in the morning.

2) It is sedating me somewhat, and I seem more tired than usual.
(this is unexpected)

3) it does cause some nausea when I first take it. I mix it into
Crystal light. It is not unpleasant in any way taste-wise, and is similar in that way to inositol powder.

4) I am sleeping much much better. I don't understand this effect either.

5) it is reducing my appetite and food does not seem attractive very much at all. If this continues, I might be losing substantial weight. (that would be a plus!)

It is VERY hygroscopic...meaning it turns to liquid when exposed to air. The little powder residue left on the scoop which I left out because the handle is so long, turned to a clear syrup. So storage of it is important. ( I had to carefully clean that up before using again).
I am thinking of putting the jar in a plastic ziploc too.

Too soon to tell if it is working on pain at all, or stamina, tho.
