Brutal but predictable

The 7-OH withdrawal timeline, day by day

Withdrawal feels chaotic — but it follows a predictable curve. Knowing what's coming, and when it ends, is half the battle. Here's the map, plus a coach for the hard hours.

First 36 hours — onset to peak

Symptoms start within 6–12 hours and climb to a peak around hours 12–36: restless legs, sweats and chills, nausea, insomnia, and sharp cravings. This is as bad as it gets — and it crests.

Day 3–5 — the turn and the crash

The body quiets, but an emotional wave arrives around day 5 — heavy sadness and low motivation as your brain rebuilds. It's predictable and temporary, and it's when support matters most.

Week 1–4 — surfacing and PAWS

Sleep and appetite return; post-acute waves roll in shorter and weaker each time. Patience is the whole game now.
