Has anyone used Low Energy Neurofeedback System (LENS) therapy?

Recently, a friend of mine with 20+ years of brain, concentration, muscle tension and twitching and brain fog problems told me for the first time in 20 years in felt "normal" after 3 sessions of lens with a practitioner in SF. I was wondering if anyone has experience with LENS (Low Energy Neurofeedback System (LENS) therapy) and if it can assist with TMS / pain reprocessing therapy?

In the book "The Healing Power of Neurofeedback: The Revolutionary LENS Technique for Restoring Optimal Brain Function", the author who trained with Lens Ocks talked about how it helps patients with fibro and other pain symptoms.

I've been practicing TMS but still in pain, so I'm still searching for solutions.

Thanks for feedback!
