The Fear: Why You Wake Up Dreading What You Said Last Night

Your eyes open and the dread gets there before you're fully awake. What did you say to her? Why did you send that message? Your phone is face down on the bedside table and you can't bring yourself to turn it over.

Plenty of people know this feeling as the fear. It sits on top of the headache and the dry mouth, and some mornings it's the worst part. Here's where it comes from, why memory gaps make it so much louder, and what to do with it.

The hangover that lives in your head

Hangover researchers have a name for it: the moral hangover. In a consensus statement on how hangovers should be studied, an international group of researchers described guilt and shame as moral hangover symptoms that show up in real life but are hard to recreate in a lab. Finnish has its own word for it. Kielitoimiston sanakirja, Finland's standard dictionary, defines morkkis as slang for a moral hangover and self-reproach.

It's a common experience. In a survey of 800 Dutch students cited in that consensus statement, 38% said they had said or done embarrassing things while drinking in the past year. When researchers in England analysed how young adult drinkers wrote about drinking too much, the emotions that came up on the downside were mainly guilt and embarrassment.

How it differs from hangxiety

Hangxiety is mostly chemistry. As alcohol leaves your system, your brain goes through what NIAAA, the US National Institute on Alcohol Abuse and Alcoholism, calls a mini-withdrawal, which can bring restlessness and anxiety. You can get it after a quiet night where nothing happened. Our post on hangxiety covers that side.

The fear has a subject. It attaches to specific moments: the joke that landed wrong, the text, the argument by the bar. In practice the two are tangled together. An older study of more than 1,100 social drinkers found that guilt about drinking predicted hangover symptoms over and above how much people drank.

Why memory gaps make it worse

Alcohol can block your brain from moving memories from short-term into long-term storage. NIAAA describes two kinds of blackout. In a fragmentary blackout, you have islands of memory with gaps between them. In an en bloc blackout, the memories never form at all, so there is nothing to recover later. Drinking fast, drinking on an empty stomach and binge drinking all make blackouts more likely, because they push blood alcohol up quickly.

A gap is fertile ground for dread. You can't check a moment you don't remember, and it's easy to fill it with the worst case. The same high blood alcohol that causes blackouts also weakens impulse control and judgement, according to NIAAA. The NHS notes that drinking can lead you to make decisions you regret.

What to do that morning

• Look after your body first. Drink water, eat something gentle and rest. MedlinePlus notes that recovery from a hangover is usually a matter of time.
• Check once, with one person. If a friend was there, a short message asking how the night went can tell you more than an hour of replaying it alone.
• Hold off on long apologies until you're clear-headed. If you did hurt someone, a short and specific apology later in the day is easier to get right than a long message sent at 7am.
• Don't drink to shut it off. In a diary study of social drinkers, people who went past their own limit felt more guilt the next morning, and that guilt was linked to drinking more, getting drunker and breaking their limits again.

Replaying it won't change much

Going over every detail can feel like a kind of penance, as if suffering enough will stop it happening again. The research doesn't back that up. In a study of 334 Canadian students, those who had more unwanted, intrusive thoughts about the previous night's drinking while hungover kept binge drinking more often a month later. Wanting to drink differently, on its own, didn't predict a drop in heavy drinking either.

A more useful move is to treat the feeling as information and then put it down.

What the fear may be telling you

In that diary study, guilt was strongest on mornings after people had gone past a limit they had set themselves. So the fear often points at a gap between what you meant to drink and what you drank. A few questions can turn it into something useful:

• How much did I plan to drink, and how much did I have?
• Was there a point where the night tipped? What was going on then?
• How many mornings like this have I had in the last few months?

If memory gaps are part of the pattern, take them seriously. NIAAA says a blackout isn't necessarily a sign of alcohol use disorder, but even one is a reason to think about your relationship with alcohol and talk to a health professional. Our drinking self-check is a private place to start.

Making the next morning different

The fear tends to follow nights that went past your limit, so the change that matters happens before the first drink. The NHS suggests deciding on a limit before you start, eating first, alternating alcoholic drinks with water or soft drinks, and choosing smaller or lower-strength drinks. Telling a friend what you're aiming for gives you some backup when the next round arrives.

If you decide to cut back for a while, one safety note. If you drink heavily every day, stopping suddenly can be dangerous. Talk to a doctor first. And if a night still goes further than you meant it to, what to do after a drinking slip has a calmer way through the morning after.
