I do not know to what I can attribute the same change, but I do notice a difference in a big way! There were many days I hated facing the morning and wished I could keep sleeping. When I DID get up, I was lethargic and could not get myself to do all the things that needed to be done.
Now, I am practically full of energy, looking for things to do so that I can be active. Rake lawn, prune trees, straighten the woodpile, oh I can think of lots of things I do. Love it and I know my husband loves the difference, too.
