The Stellate Ganglion Block: Chris Williamson's Nervous System Reset

Does Tim Ferriss Dream In Japanese? - Rabbit Hole #3 - #1105 · Jun 1, 2026 Health & Fitness

A stellate ganglion block involves an ultrasound-guided anaesthetic injection into a nerve bundle in the neck, essentially shaking the etch-a-sketch of your sympathetic nervous system. Chris Williamson tracked a 30% overnight increase in HRV that held for months. It's primarily used for PTSD in soldiers. You do one side, wait, then do the other — because both at once would shut down half your face and throat.

How Tim Ferriss Went From a 9 to a 1 on Anxiety

Does Tim Ferriss Dream In Japanese? - Rabbit Hole #3 - #1105 · Jun 1, 2026 Health & Fitness

Tim Ferriss used accelerated TMS combined with the neuroplasticity agent D-cycloserine to drop his generalised anxiety and OCD rumination from an 8-9 out of 10 to near zero — in a single day. The effects lasted three to four months. It changed how fast he fell asleep, how easily he meditated, and how he processed the friction of daily life.

The TMS Side Effect Nobody Warned Tim About

Does Tim Ferriss Dream In Japanese? - Rabbit Hole #3 - #1105 · Jun 1, 2026 Health & Fitness

After his first successful TMS treatment, Tim Ferriss couldn't ejaculate for two weeks. His doctor had never seen it before and attributed it to over-suppressing the sympathetic nervous system. The good news: anxiety gone. The bad news: something else gone too. Eventually it resolved — and now he knows to expect it as confirmation that the treatment worked.

Vagus Nerve Stimulators: Most Are Bunk

Does Tim Ferriss Dream In Japanese? - Rabbit Hole #3 - #1105 · Jun 1, 2026 Health & Fitness

Most non-invasive vagus nerve stimulators don't hit the nerve correctly. The nerve fibres barely reach the ear, and most ear-based devices aren't positioned in the right spot — the cymba concha. The neck-based devices are more promising and are FDA-cleared for migraines. But Setpoint Medical's implant — the size of an omega-3 capsule, inserted as an outpatient procedure — is the real frontier.

The Radiology Lesson: AI Replaced the Part That Was Never the Point

Why Storytelling Is Now the Most Valuable Skill in Tech · Oct 14, 2026 Health & Fitness

Predictions that AI would eliminate radiologists were spectacularly wrong. Since those predictions, Mayo Clinic's radiology staff grew 55% and the specialty became the second-highest paid in medicine. The reason: AI automated scan-reading, but only 36% of a radiologist's time was ever spent doing that.

The Worry Time Technique

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.

Glad You Did It Activities vs. Mindless Scrolling

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
