I am very gluten sensitive too, so was wanting to avoid the grain alcohol. I saw that the company you are ordering from has a St. Johns wort tincture too, which I would love to try also. Man though, it can get expensive, but worth it no doubt if it works.
If this does work, and I get some energy, I've got to learn to make my own. I've got some potato vodka sitting in the cabinet I could use. :)
