Perhaps we are taking it for different reasons. I also don't take it as directed because of its potency. I started because of the alpha lipoic for SFN and now it is more of a maintenance for blood vessels. Like you, the EB-N5 jury is still out. Nothing has "cured" the SFN. Not to sound like a lunatic, but I also have been using red light therapy and a grounding mat. I prefer natural healing methods when possible, rather than synthetic drugs with so many side effects. Be well!
