A transient ischemic attack (TIA), or ministroke, occurs when part of the brain experiences a temporary lack of blood flow. This causes stroke-like symptoms that resolve within 24 hours. Unlike a stroke, a TIA doesnât kill brain tissue or cause permanent disabilities. Since symptoms of a TIA and a stroke are nearly identical, you should seek immediate emergency attention if you experience any symptoms.
Starting from this BAC, your body needs almost 14 hours to completely metabolize the alcohol. Of course to pass the breathalyzer in all 50 states, your BAC needs to be under 0.04. A 0.04 will not get you a DWI (driving while intoxicated), but you can be charged with a DUI (driving under the influence). To legally pass the breathalyzer after 12 beers in three hours, you need a little over 11 hours.
Alcohol itself stays in your system for 1-1.5 hours for each drink you take, plus approximately 1 hour delay for the initial drink -- this is when it's detectable in breath and blood, and when it will affect you. It then stays in your urine for another hour or so, where it's detectable in a urine test.
