In Spain, McDonalds sell beer! I always find a quarter pounder with cheese, large fries, and a beer sets me up for another drink in no time.

Seriously, though, getting some fresh air is also good. You'll feel much better after a 10 minute jog, because it gets all the poisons moving around and eliminated

If you can't get URAL try some dexsal? or whatever fizzy stuff people drink for indigestion where you are. Drink lots of water as part of the hangover is dehydration. Try to get some extra sleep, and put off any major work or life decisions until you feel better, because a hangover affects your judgement as well.

Hope you feel better soon!

If I try to explain what alcohol does when its in your system, it'll make finding a hangover "cure" a whole lot easier.

Alcohol is in terms on nutrients, a carbohydrate. It is a simple carb in the way white sugar is a simple carb (its made from fruit sugars and this is why its a simple carb.) It does what all simple sugars do (ever heard of the g.i diet?) it raises your blood sugar to very high, thn when its left your system, it plunges to very low and in response your body becomes weak and tierd and you feel nausious.
Simple cure? something which has both simple and complex carbs in it- such as mulitgrain bread (n.b not brown bread which is just a simple carb) and maybe a glass of orange juice.
Second, when drinking alcohol your body looses fluid andyou become dehydrated- simple cure? dinkk some water.
Third, your body sweats more than usual when drunk as your metabolism rises with all the alcohol sugars you take in. when you sweat, you not only loose water, you also loose blood salts, so a small amount of slat is what your body needs- you can get this through drinking an icotonic drink like lukosade original or a rehydration packet which are from boots.
Fourth, you need- when having ingested all of the above, so sustain the blood sugar and metabolism which can only be done by eating something with fat in it.

So in summary you need to eat something with both simple and complex carbohydrates in, something with a small amount of salt in, drink some water and rest.

BLT on multigrain bread with orange juice and tea it is then!

It depends on the severity of the hangover, if its mild quit moping around and do something to take your mind off it. If its a bad one take it easy a bit – maybe a quiet walk out, or go for a swim.

Some people follow the "hair of the dog" practise (drinking more alcohol while still hungover) I dont see how it works as you eventually have the impeding hangover to deal with as well as the weight gain.

Whatever you do. Drink lots of water.
