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 UK had 12,183 arrests for posting on social media in 2023 — nearly double second-place Belarus — according to Freedom House statistics cited in The Times.
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.
Chris Williamson tracked a 30% overnight increase in HRV after a bilateral stellate ganglion block, which held for several months before gradually declining.

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.
