Drink driving – you're breaking the law if you drive and your blood alcohol concentration equal to or more than 0.05. If you're on a learners or provisional licence, your BAC must be zero.
A BAC of 0.02 can be reached after the consumption of only one standard drink (a middy of beer, a nip of spirits or a small glass of wine). Drivers subject to a 0.02 limit should not drink any alcohol before driving.

The Standard 1-Hour per Drink Rule
Usually, you are safe to use the one-hour per drink rule. So, if you have two glasses of wine, you should wait two hours before driving. When you do an hour per drink, your body has time to overcome the other factors listed above, and hopefully, you have a safe enough BAC to drive.
The standard amount of wine to get drunk is usually around 3 to 4 glasses. It's because the Blood Alcohol Content (BAC) will reach the minimum amount of drunkenness at 0.25 percent.
'Alcohol irritates the stomach wall causing inflammation, known as gastritis,' she continues. 'This is exacerbated by an increase in the production of stomach acids. This gastric upset often results in vomiting.
If a person experiences diarrhea more when they drink wine, they may have an allergy to tannins.

The general rule of thumb is that 2 standard drinks in the first hour will raise your BAC to 0.05%, and 1 standard per hour thereafter will maintain that level. To do a quick calculation of whether you are over 0.05% BAC, simply take the number of hours since your first drink and add 1 to it.

Keep a drinking diary: Many people find they are well within safe levels (75 percent of the women in our poll reported having fewer than four drinks per week).

But red wine's typical strength means drinking two large glasses in one session could mean you're consuming six and a half units of alcohol, so could be classed as 'binge drinking' (more than six units of alcohol for a woman, or eight for a man).
Alcohol detection tests can measure alcohol in the blood for up to 6 hours, on the breath for 12 to 24 hours, urine for 12 to 24 hours (72 or more hours with more advanced detection methods), saliva for 12 to 24 hours, and hair for up to 90 days. The half-life of alcohol is between 4-5 hours.
Generally, a breathalyzer test can test positive for alcohol for up to 12 hours after consuming one alcoholic drink. The average urine test can also detect alcohol 12-48 hours later. If your BAC is 0.08, it will take approximately 5 hours to metabolize the alcohol completely before you can become “sober” again.
0.10 – 0.12% – Obvious physical impairment and loss of judgment. Speech may be slurred. 0.13 – 0.15% – At this point, your blood alcohol level is quite high. You'll be affected by blurred vision, loss of coordination and balance, and potentially dysphoria (anxiety or restlessness).
