Alcohol is distributed around your body by your blood as you drink and even the smallest amount can have a physiological effect. You’ll lose a small amount of alcohol as it leaves your body in your breath and urine but your tolerance will depend heavily on how much you’ve had to eat. Food that is high in fat slows down the absorption of alcohol into your bloodstream and it will take longer to feel intoxicated although there are other, more damaging effects of alcohol on your overall health to take into consideration.
