Clinical assessments, including self-reported measures, are often used to quantify alcohol use. Self-reported measures such as the Alcohol Timeline Followback (TLFB) instruct individuals to recall daily drinking over a specified period of time, using anchors and memory aids to enhance recall [5].

In fact, attempting to speed up the process through excessive water consumption or other methods could be dangerous, potentially leading to vomiting and dehydration or other health issues. FAEE are non-oxidative metabolites of ethanol that are produced from triglycerides or free fatty acids by FAEE synthases and other enzymes [36].

With less ADH in their bodies, women tend to metabolize alcohol slower than males.
