The Start-Tomorrow Toolkit

One page. The vagus-nerve practices that actually hold up to the evidence — pulled straight from The Vagus Nerve, Decoded. No “reset”, no “detox”, no 60-second miracles. Just what works, graded honestly.

• Five practices, graded A–D by the real evidence — from slow breathing (A) down to the famous “hack” that scores a flat D
• The overhyped gear to skip — ear-clip “stimulator” gadgets, “vagus-toning” supplements, and the one-trick cures
• A one-minute start-tomorrow plan — morning, daytime, wind-down. No equipment, no app, no gadget
• The safety lines that matter — when not to push, and what to take to your own doctor
