KNOW YOUR LEGAL LIMIT
In Texas that means .08% of Blood Alcohol Content or any amount which results in loss of normal use of mental or physical faculties. This is only a guide and NOT sufficiently accurate to be considered legal evidence. The figures you calculate are averages. Individuals may vary somewhat in their personal alcohol tolerance. Food in the stomach affects the rate of absorption. Medications, health, and psychological condition are also influential factors. In any case, if you've been drinking at all, be careful!
