Here's a peek inside...

  • Long COVID often stems from four hidden disruptions in your body:

    Misfiring nervous system (dysautonomia), low cellular energy (mitochondrial dysfunction), an imbalanced gut (gut dysbiosis), and immune overactivation (excess histamine and mast cell activity). But you must figure out which ones.

  • If standing makes you dizzy or your heart races...

    you may have POTS—a form of dysautonomia that drains your energy and clarity. You'll show you the signs.

  • The Stellate Ganglion Block (SGB)

    is a breakthrough nerve-reset procedure that can calm your fight-or-flight response—relieving brain fog, fatigue, and sensory overload in many Long COVID patients. But not all practitioners understand the proper placement. Proceed with caution.

  • When your cells can’t make enough energy...

    you feel like your battery’s always low. Mitochondrial dysfunction is often behind this—and can be reversed with a four-part plan. Get the full details.

  • Chronic inflammation in your throat can ...

    quietly fuel fatigue and headaches—Discover the protocol for stimulating the vagus nerve to help calm this hidden source of stress.

  • Want real-time insight into your recovery?

    Heart Rate Variability (HRV) tracking reveals how your nervous system is coping and helps tailor your healing plan. But you must know what to look for or you're flying blind.

  • Long COVID hits multiple systems at once...

    most patients report 15–18 symptoms ranging from brain fog and breathlessness to gut issues and heart palpitations. You better have a proven diagnosis system if you want to enjoy recovery.

  • Certain people are more vulnerable...

    to Long COVID, especially women, those with prior nervous system issues, and anyone who had five or more symptoms during their initial COVID infection. Do you know which symptoms?

  • Why you should NOT avoid delaying treatment...

    Long COVID can age you faster—literally. Chronic stress and mitochondrial damage accelerate biological aging, but this trend can be reversed by calming the nervous system and reducing oxidative stress.

  • When kids have Long COVID...

    the symptoms often go unnoticed. Fatigue, headaches, and gut pain can be hard for children to explain—but there are solutions that work for them too.

This book puts it all together. Things I’ve learned here and there, but didn’t understand how and if they all worked together. I am so grateful for finding this resource and cannot wait to start treatment after two years of looking for answers. Thank you Dr. Groysman!

This book is one of a kind. I wish there was a Handbook like this for every illness! Dr. Groysman thoroughly explains the medical science of Long Covid and well-researched treatments. For those of us with brain fog, it is easy to read without losing key information. I can’t recommend this book highly enough. After 2 years of struggling with this crazy illness my doctors know very little about, I now have a detailed Handbook!

This book convinced me to truly give him a chance and I booked my new patient appointment. I already had VERY bad disability (lots of it!) so I pray he can help me get back to a better quality of life for my family and my survival! I believe Dr. Groysman is truly gifted by God and I wouldn’t recommend him and this book if I didn’t think so. Buy it and book your consult if you need it!

I am a Physician Assistant who had 2 family members suffering with Long COVID related symptoms. I was so excited to start reading this series he has published with all his research gathered in one spot. The book was easy to read and understand and touched on many of the areas being researched in relation to long Covid. I highly recommend this book to any long COVID sufferer, family member or medical practioner.

Frequently Asked Questions

Is it useful if I also have ME/CFS or POTS?

Yes—protocols overlap and are clearly flagged. The handbook addresses common mechanisms between Long COVID, ME/CFS and POTS, with specific guidance for each condition.

Does it cover Low Dose Naltrexone and Vagus Nerve Stimulation?

In depth, with starting doses and titration tables. You’ll find comprehensive information on protocol implementation and expected outcomes.

Do I need a doctor?

Some treatments (e.g., SGB) need one; many lifestyle and supplement steps you can begin today. The handbook clearly indicates which protocols require medical supervision.

How is this different from other books?

Others spotlight one system; this integrates four, based on 4,000+ patient cases. The handbook provides a comprehensive approach addressing multiple root causes simultaneously.
