Less often beats less

Most advice about drinking is about quantity. Have fewer. Make them smaller. Swap one for a water. All sensible, and all beside the point for the person this is written for, who has two or three wines most nights and never a scene.

The problem with most nights is the word most. A body that gets alcohol six or seven evenings a week never gets a run of nights to do the things it does when there is none to deal with. Sleep is the obvious one: a couple of drinks gets you off to sleep faster and then wrecks the second half of the night, and if that is every night, you are never properly rested and have forgotten what rested feels like. The liver gets a similar story. So does your tolerance, which creeps up when the gap between drinks never widens, which is how two wines quietly becomes three.

Nights off change all of that without asking you to change what a drink is. Four clear nights a week is four nights of better sleep, four mornings that start on time, and a tolerance that drifts back down so the Friday glass tastes like it used to. The maths helps too. Two glasses on three nights is six a week. Two glasses on seven is fourteen. Nobody cut down; they cut nights.

There is a second reason the night is the right unit, and it is about honesty. Counting drinks invites fudging. Was that a big pour? Does the half at the end count? A night is harder to argue with. Either there was alcohol or there wasn’t, and you know which.

What a shape is

A shape is the set of nights you intend to keep clear each week. Spacer suggests Monday to Thursday because it has the best chance of sticking: those are the nights with the least social pressure and the earliest alarms. Some people start with three. Some, who have decided to stop altogether, pick all seven, and the app treats that the same way, as a shape to keep.

The rule for choosing is the same for everyone. Pick the shape you can hold for four weeks, not the one that sounds best. A kept shape of three nights does more than a missed shape of five, because the kept one is still there next month.

What happens on the other nights

Whatever you like. A Friday with the usual crew is a Friday with the usual crew. The app will ask you how it went the next morning, and “a big one” is an answer like any other. That log is not a confession. It is the thing that makes the clear nights mean something.
