The best (physiologic) way to prevent yourself from getting too drunk.

I have a problem with my brakes when it comes to alcohol.  I rarely drink, but when I do I don't stop.  This is fine for the most part but if I am at an event where I'm expected to remain socially coherent, I need to do everything I can to make it to closing time before my fiance is holding my hair back.  There are many home remedies, but only one that is scientifically proven - eating a greasy meal before drinking.

The limiting step in absorbing alcohol is gastric emptying, or how fast alcohol leaves your stomach. The majority of alcohol absorption occurs in your small intestine, which if you are not anatomically inclined is just down the road from your stomach.  Once liquor gets here its fast-tracked to the blood stream. Therefore, the longer you can keep that shot of tequila in your belly, the longer you have to break down whatever you drank that made you think tequila was a good idea.

Greasy food is better than anything at slowing gastric emptying for the simple fact that fats are difficult to break down. When a cheeseburger hits your duodenum, a sort-of pouch where fat digestion takes place, a hormone called cholecystokinin (CCK) is released.  CCK does two things: it signals the pancreas and gallbladder to release more enzymes to help dissolve the fat, and it tells the stomach "Slow down for a bit, I have my hands full here." The stomach's sphincter tightens up and presto, the flow of alcohol slows to a trickle.

As most people intuitively know, the reverse of this method is also true.  If you go drinking without eating, the stomach is a wide open pipe and alcohol is going to be absorbed super fast.  The trick to avoiding this situation is eat your meal twenty minutes before you plan on imbibing, to give the food time to start to digest.

Hangover Science Time!

Most everyone knows what a hangover feels like, but few know exactly what is going on in the body. "Why does my head hurt?", "Why am I so shaky?", and "Why can't I fall back asleep?" are all common questions that go along with a night out on the town.  Here is a scientific explanation of just exactly how deranged your body becomes after intaking too much alcohol.

Firstly, yes a major part of a hangover is dehydration. Alcohol inhibits a hormone called anti-diuretic hormone. Its what your body releases to tell the kidneys "Hey! stop pissing out all my good water." This is why when you "break the seal" you pee out huge amounts of nice clear urine. The kidneys are not concentrating the urine but are just letting all the fluid that reaches them go to the bladder.

However, you're not going to stop a hangover just by replacing fluids. Alcohol is metabolized into acetic acid, but on its way it becomes something called acetylaldehyde. Acetylaldehyde is the nasty toxin that makes you ache the next day and gives you the water on the brain feeling. How quickly you metabolize this chemical depends on genetics and duration/frequency of alcohol exposure. Many alcoholics don't get hangovers because their body has produced enough metabolic enzymes, called acetylaldehyde dehydrogenase, to clear away this chemical before it affects them. Lots of Asians lack this enzyme and the acetylaldehyde builds up quickly - hence they flush red and feel sick with just a few beers.

Just to hammer this point in, Disulfuram is a medication given to alcoholics to help them control their drinking. It is nothing more than an enzyme that instantly converts alchohol to acetylaldehyde. If someone takes a drink while on disulfuram, instant hangover.

And there's more. Alcohol also inhibits glutamate's effect on the brain. This amino acid is used to by your body to stimulate you and wake you up. When alcohol stops it from working, your body releases a TON of glutamate to make up for it. What sucks is that your body clears the alcohol away faster than the new glutamate. This means that all of a sudden, the extra glutamate you released, plus the glutamate you had before, are no longer being inhibited. This is why you can be tired as hell after a late night drinking but still wake up early and not be able to fall back asleep. Its your body's revenge- "No way you're going to sleep this off, you stay awake and think about what you've done."
