喝酒后的反应主要是看身体内的酶对酒精的分解（以肝脏为主）。科学的衡量一个人是否喝多了是测验血液中酒精的溶度。比如说你心情好和不好的情况下喝同样数量的酒，在警察的呼吸器那里的结果是差不多的。所以警察给你开罚单只根据测试数据，不会理睬你心情如何。
人的情绪的确对人生理上有很大影响，比如体内酶的数量和活跃程度。从这个角度讲情绪会影响一个人的酒量。但两者的具体关系我想是因人而异的。比如我的情绪对酒量就影响不大。
喝酒后的感觉是个很主观的东西。兴奋的时候你喝了不少而感觉很好。你调整的不是你的酒量，而是你的主观感觉。
情绪的好坏还直接影响你喝酒的方式。比如心情不好的时候，可能闷头喝，间歇短，速度快，又不怎么吃菜来缓冲一下，所以同样的酒精给你的反应就不一样。
借酒消愁愁更愁。喝酒的乐趣在于Enjoy。如果你没有这种心情，最好不要喝。否则难受的是自己。
Alcohol molecules are different than most food and drink molecules because they can pass into the blood without being processed by the digestion system.
For example, after eating a hamburger, the stomach takes time to digest the beef into its constituent amino and fatty acids, which then enter the blood. Alcohol is able to enter the blood directly through the mouth, stomach and small intestine where it remains chemically unchanged in its composition from when it was swallowed.
Alcohol will be absorbed into the blood more quickly if the stomach happens to be empty. This is because the valve that connects the stomach to the small intestine is not closed, and the alcohol can enter the small intestine, which leads to very rapid absorption. If the stomach is busy digesting a lot of food, the valve will be closed and the alcohol cannot proceed to the small intestine as quickly.
Once the alcohol reaches the bloodstream, it takes less than two minutes to reach the brain and affect the central nervous system. Alcohol is also a diuretic, meaning that it causes the body to lose water through urination.
The liver breaks down 90 percent of consumed alcohol into other chemicals that the body stores. Five percent is exhaled in the breath and 5 percent is excreted in the urine. These three methods of removal allow the average person to eliminate 14 grams of ethanol per hour. Twelve ounces of beer, five ounces of wine, or 1.5 ounces of hard liquor all have about 14 grams of ethanol in them, so the average person eliminates one drink per hour.
