Apart from the obvious toxic effects, you should realise you're suffering the effects of a mild overdose of a depressant drug and your nerves are reacting accordingly, and you have also flushed a signifnicant quantity of vitamins and nutrients from your system causing a degree of metabolic shock that your body is struggling to compensate against..
This is why hangover symptoms often include disorientation and "the jitters"..
Some drinks give you worse hangovers than others due to the actions of impurities called Congeners..
While it's the ethyl alcohol (ethanol) that gets you drunk, amyl alcohol, butyl alcohol, methyl alcohol, propyl alcohol, and isopropyl alcohol is also found in most drinks to varying degrees, and the concentration of these Congeners will go a long way to determining the severity of the hangover..
Vodka and gin (clear liquors) are generally lower in congeners than whisky, rum and bourbon, due to the filtering process involved, and hence usually give a less intense hangover..
Unfortunately the congeners also give flavor, smell and appearance to alcohol..
Another contributor to the hangover is the "freshness" of the alcohol since the natural oxidation product of ethanol is also acetaldehyde..
Finishing off an already open bottle of red, or drinking beer that's been in the boot of your car for a week, will provide you with a ready made supply of acetaldehyde so you don't have to wait for your liver to make it in order to have a really good hangover..
Most hangover "remedies" simply attend to one or more of the symptoms and don't really provide a cure as such..
The hangover won't stop until the alcohol is out of your system:* Berocca - Puts the vitamin B back in, as well as the big glass of water it's mixed with..
It's probably best to do this before you go out..
* Coke - Fizz for the nausea,white gold earrings liquid for the dehydration, and a caffeine and sugar hit to make you feel a bit more lively..
* Coffee - Same as Coke but without the bubbles to help ease the nausea..
Try it with honey instead of sugar since the fructose is absorbed quicker than the sucrose in normal sugar, and it's better for you..
* Ginseng - It's been noted that since caffeine is a diuretic like alcohol, it can actually make the dehydration worse, so try the herbal equivalent instead..
* Vegemite On Toast - Something in your stomach is good, and salty is even better..
Plus you get a Vitamin B top up..
The same reasons also make peanut butter a good choice, but the oily nature might make some sensitive stomachs feel a bit yucky..
If you do try try this one, skip the butter and just have dry toast..
* Cold Pizza - Who knows, but it seems to work..
* Asprin - Simply attends to the headache and does nothing for the level of alcohol in your system..
Don't take them before you go to bed..
* Bananas - Sugar in the form of fructose, and potassium, which is one of the things you lose lots of when you drink..
Bananas are also a natural antacid to help with the nausea, and are high in magnesium which can help relax those pounding blood vessels causing that hangover headache..
For a variety of reasons try a peanut butter, honey and banana sandwich on white bread..
* Vitamin C - Another thing the alcohol takes out that you're advised to put back in as soon as possible..
Orange juice, tomato, a 600mg Vitamin C tablet - doesn't matter, just do it..
