7 days. 7 nudges. A habit that finally sticks.

A free, 7-email behavioral science series. By day 7, drinking 2L feels automatic. Plus 10% off your first Nudge bottle.

What's in the 7-Day Nudge:

Day 1: Why "drink more water" advice never works (and the 90-second trick that does)

Day 2: Habit stacking — pair drinking water with something you already do

Day 3: The dehydration symptoms most people misread as anxiety, hunger, or fatigue

Day 4: Why morning hydration matters more than evening hydration

Day 5: The bottle-on-desk experiment (visible cues + the 7-day rule)

Day 6: What 2L a day actually does to your skin, focus, and energy

Day 7: Make it permanent — the daily ritual that locks the habit in

Built on real behavioral science.

This series is based on the habit loop framework from Charles Duhigg's The Power of Habit, BJ Fogg's behavior model (Stanford), and James Clear's Atomic Habits. Nothing here is a wellness influencer's opinion.

You don't need more motivation. You need a better cue.

Founder note

"I forgot to drink water for six years. Coffee, headaches, brain fog by 3 pm — I assumed it was just adulthood. Then I tried every hack: alarms, apps, "drink a glass before every meal" rules. None of them stuck.

The thing that finally worked was a bottle with markers on the side. Stupid. Obvious. Boring. And it worked because hydration was never a willpower problem. It was a visibility problem.

I built Nudge because I wanted a brand that took the boring fix seriously, instead of selling me a $40 tumbler with a cute colour."
