Driving the day after "a session"

[J4CKO]

Went to see the Stone Roses in Manchester last night with all the other sad old 30/40 somethings in Kangol hats, I dont generally drink that much but had a fair few beers and a few Vodka and Cokes, I feel fine today (remarkably) but was wondering what is the longest after finishing drinking at say nine/ten pm last night that alcohol could be in my bloodstream ?

Not going anywhere, but how long after would it still be possible to be over the limit ?

Obviously it's entirely dependent on you, your metabolism and exactly how much you drank. Little reusable breathalysers are readily available these days and pretty bloody useful too, but the rough guide for whoever the "average" person might be is that one unit of alcohol will be metabolised in around an hour.

[z4chris99]

5 pints plus 3 vodkas = 14/15 units.

stopped drinking at 9, it's now 14 hours later.

man maths says you'll be ok.

Yes, very difficult to determine and not something to leave to chance, wonder if anyone has been done the day after the day after the night before ?

Have completely forgotten exactly how much I did drink.

What were you drinking to get done 48 hours later, methylated spirits?

My mate got done @ 15.00 the day after we had a sesh.

Yes, I tried one after 3 pints of Stella and was nowhere near being over the limit.

^^^^^^^^^^^^^^^^^^^^^ this we d been out all day from 11am went home at just about 9pm lad who i was out with went in to town the next day at 3pm and blew red on the road side and was clear when he got to the station.

Fair to say hes never shat himself so much in all his life, and hes never drove at all the day after since.

Me personnally, i do what has been stated above with the man maths except 14/15 units and now 14 hours later i always allow an extra couple of hours, due to as again has been stated everybodys body gets over alcohol differently in terms of time etc.

That is all

Hmm, I used to work at the Police and we set up the software for the "Lion Alcometers/Intoximeter" so we had one in the office for testing purposes, we also had a pub over the road, also for testing purposes so we would go and have a couple of pints and then try it, two pints it was yellow, three it was most definitely red and I was cock all use all afternoon, alternatley, peeing, making brews and getting a bit flirty with a woman 15 years my senior in the office.

A huge amount depends upon how big you are, how much water you drink, whether you are eating at the same time and your metabolism.

IMO one of the riskiest things to do in terms of going easily over the limit is,

• At work all day Friday
• Not much lunch
• Off to pub after work 6.00 pm for "just a couple of beers"
• Jump in car 7.00 pm to drive home.

Some people have claimed to be over the limit after drinking a couple of very low alcohol (1%) beers but they are not believed in court when they try to blame the brewery. Technical guys in the beer industry don't have hard and fast facts but they think it's practically impossible to go over the limit on those beers because you can't drink fast enough and there's so much water in there. Best not to try it though. However, drink enough orange juice that's going off a bit and you could be in trouble with some of the low limits on the continent.

If you drink three pints quickly and then blow, you might come in under the limit. Half an hour later, however......

Based on my experience of several BTaP's, there's seemingly little consistency to the results.

Some people who were absolutely hammered at night blew 0 at 9am, and others who seemed sober were still well over.

[anonymous-user]

When doing the calculation rember the first unit takes 2 hours to metabolise and then it's 1 hour per subsequent unit.

So, on average, it takes 14 hours to get rid of 13 units

[anonymous-user]

I use the 1 unit per hour rule (or not drive at all), but I'm not big (68kg, 180cm) so I need to be careful. I have a high metabolism and always eat lots of food because of that so I would hope that helps, but who knows!

I would definitely buy a reliable home breathaliser.

I believe a regular drinker's liver sits ready with appropriate enzymes to break down the alcohol. The liver of an occasional drinker has to work from a standing start.

The catch for regular drinkers is they can feel/appear pretty sober while being well over the limit.

The rate of absorption of alcohol into the bloodstream is the same whether a given individual has been a regular drinker or a non-drinker. Since the breathalyser doesn't care which you are, caution is needed by regular drinkers who drive. Statistics apparently show equal impairment of reactions for a given blood alcohol level whether you are a regular drinker or a non-drinker. In other words, how you "feel" is pretty much irrelevant.

When I was younger I was out with my mates on a sesh and jumped on the last bus home, this would have been 11.15 so last drink around 11pm.

Jumped in the car the next day before 11 am to head to the park for a kick-about (stupid decision as it was a 10 minute walk). As it was just through the village I never bothered with my seat belt either (never do that now-a-days). My mate spotted a police car coming along the road we were turning on to through the trees and I ended up mounting the kerb as I turned the corner trying to haul my seatbelt on which got spotted. The police car turned round and found us at the park. Got breathalised and he knew from my look I was expecting to fail, was very honest that I'd been out the night before and probably shouldn't have driven. Got the full lecture and told that I was going to have to wait for a police van to come and get me once I'd failed, needless to say I was absolutely delighted that I passed but boy did that give me a fright!

I know there's a one hour per unit general rule but do you also take into account when you start and finish drinking in that equation? Since that night I've had a general rule that the minimum is 12 hours after I stop drinking but that all depends how big the night out was and how much I've eaten through the day how much more than the 12 hours I leave it.

There was a similar thread a whole back.

Didn't go well for the OP iirc.

So hypothetical question.

If i start drinking at 12 noon, and drink one unit (half a pint) every hour until 12 midnight, when would the average person be able to drive again?

Lightweight, that's only six pints!

To be fair you aren't far from the truth...... My drinking daze are well and truly over ( at least compared to what i used to)

But given that scenario would you drive at 1am?
