What is the most I can drink at night without being over the limit next morning?
Each person handles alcohol differently. The answer to the question depends on what you drank and when you started. You need to count the units of alcohol you consume and the number of hours since you consumed it. eg a bottle of wine contains 12 units (yes, that’s right TWELVE!) which takes the average person about 12 hours to digest. If you finish drinking at midnight, but want to drive to work at 8am, you are likely to have 4 units still in your system. It will affect your reactions still and your breath sample will likely be over the limit. 48% of drink drivers in S Yorkshire were caught the morning after (Xmas campaign 2007).
