OK, it might depend on a number of factors, but there must be a reasonably conservative maximum, assuming you're a tiny girl who absorbs alcohol instantly?
Also, I note the roughly in the OP.
There used to be something like a pint an hour, providing you had eaten well. Many years ago I drank 4 pints over a 5 hour period, didn't feel drunk, everything was perfect. The Police are automatically called to RTAs when the ambulance is called.
What is the drink driving limit?
In the UK the drink driving limit is:
35 micrograms of alcohol in 100 millilitres of breath;
I gave a reading of 37. 12 month ban, 100 quid fine, 10 year endorsement on my licence, lots of entertainment for the insurance companies when I tried to get back on the road (think of a number, multiply it by 2 etc…)
Not a point since though on a 27 year old licence. 😀
edit: if you think my comment above was serious….. 🙄
