Kitty, I have PN and have been taking Methyl B-12. As well as Benfotiamine. A couple of weeks after starting these 2, I started taking R-Lipoic Acid (Best stabilized). (these are recommended as a possible nerve regeneration.)

But; and the main reason for this post is - within a week or so, after starting the Stabilized R-Lipoic Acid, I started having much more energy. (also as a side benefit, did lose a few pounds too.) I am on Oxycotin, Percocet, Vallium, Abien Cr and still this really gives me an energy boost.
