By sweeping away our daily routines, the coronavirus has crashed into the scaffolding that holds up our lives - triggering a perfect storm for hitting the booze.
With nobody immune from feeling uneasy and all having to stay home, if we don't keep an eye, this lockdown could turn into one big lock-in that is going to make us feel even worse.
Go into any supermarket and it's clear people are stocking up - but how long will the beer sit in the pantry? There is no point in all of us going off the rails. Though safe drinking is, of course, absolutely essential to this outcome!
In my local SuperValu on Saturday, it seemed every second customer was grimly loading their baskets with beer and wine. When I mentioned this to the lovely employee supervising the self-service tills (heroes, every one of them) he told me that in the past seven days he would estimate alcohol sales have easily beat Christmas week.
Even German Chancellor Angela Merkel was spotted in a Berlin supermarket a few days ago with four bottles of wine in her trolley - and this was before she knew she was going into quarantine.
It seems sensible to have a decent supply of products you need. But with alcohol, the more you have, the more you are likely to tuck into - in marketing terms, it's in the expandable consumption category. Unlike, say, toilet paper - no matter how many rolls are in the house you still use a fixed amount.
In times of stress we turn to a glass of wine to calm us, and hands up who is not feeling the strain these days? We don't have our gym, GAA, golf or chat in the pub to console us and ward off dark thoughts about our own mortality.
Many have financial strains now to deal with on top of the worry about getting sick. And living in close quarters with the family means tensions are probably running that bit higher with the space and extra housework issues that come with a house full of people - not to mention the homeschooling.
In our home, the domestic sphere is usually my domain and now my partner is everywhere. If he is not instructing me how to properly cook steaks, he is spotting the broken microwave and lampshades behind the bins I said I disposed of months ago.
I'm guessing there is a bit of discord in many homes, with the quick fix often to reach for the wine to relax.
It can be worse living alone. A friend reports waking daily to a panic attack, convinced she has the virus, with nobody to talk her down, and then is on the phone all day trying to monitor her elderly parents.
She opens a bottle at night to have one glass but when watching TV finds she lowers it all. And I have lost count of the sheepish messages from other friends announcing it is wine o'clock well before 6pm.
Drinking in bars and restaurants brings logistic and solvency constraints - six pints in the pub is a lot pricier than a six pack on the sofa. Now there is no driving home or taking turns to have a drink.
With the majority of us no longer commuting, it seems likely if you have a few bottles in the house, and are one of the approximately 80pc of Irish adults that drinks regularly, you may find yourself imbibing more than usual.
Psychiatrist Larkin Feeney told me it is unavoidable that Covid-19 has left all of us feeling out of sorts.
"It is totally normal right now to feel tense, restless, unable to focus properly, and to have your sleep broken.
"People may find they are more irritable and are checking their phones more often," he said. "No doubt people will be bored and overwrought and will drink to deal with it but this will lessen our ability to cope with the stresses that we face."
To reduce anxiety, he advised people to put a structure on their day - distract themselves with little projects, avoid Covid-19-related social media and instead use their phones to ring friends or family to speak face-to-face, and to check the news only twice a day.
Right now we need the treats we enjoy, so whatever your poison is, it's probably not the time to give it up.
But deciding in advance when, and what, we will drink and to savour it is key - we need to keep within the recommended units if we are not going to lose our minds.
Take-home sales have been on the rise for years but my guess is, whenever things settle, there will be a renewed appreciation for regrouping again in pubs and chatting face to face, even if Zoom is doing a great job for the moment.
We need to look after ourselves so we in turn are capable of looking out for those who need us. And keeping tabs on the drinking will help us feel more steady and able to do this.
