Stage II is the predominant sleep stage during a normal night's sleep. The distinct and principal EEG criterion to establish stage II sleep is the appearance of sleep spindles or K complexes. The presence of sleep spindles is necessary and sufficient to define stage II sleep.
After 5 hours â your BAC would be 0.005. Alcohol would be eliminated from the body at about 5 hours and 20 minutes (the body metabolizes alcohol at the rate of about 0.005 per twenty minutes, as 0.005 x 3 = 0.015). So it is easy to tell when your body will be free of alcohol.
As mentioned, alcohol takes some time to enter your system and leaves even slower; however, 10% of it leaves through perspiration, breath and the urine, while 90% of it is metabolized. Generally speaking, alcohol leaves the body at a relatively stable pace of .015 BAC (Blood Alcohol Concentration) per hour.hen you consume alcohol, it takes some time to enter your system. Once it does, it stays in your bloodstream until your body flushes it out. Excessive alcohol consumption can play with your system and lead to impaired coordination, vision, judgment and reaction.
