Do not be fooled into thinking that a beer hangover is any different than a hangover you get from mixed drinks. It all depends on how much you drink. You can get just as drunk on beer. It is usually recommended that you do not mix your alcohol but if you must, start with mixed drinks and end with beer. If you have ever heard the saying, "Beer before liquor, never been sicker, liquor before beer, you're in the clear", then you know why. I don't know who said it but it works.
Besides, when it comes to mixed drinks they are usually made so they taste sweet and go down so well that you can inadvertently drink more than you think you do and get the really nasty hangover to go with it. The sugar in the mixers are a big contributor to your hangover. Beer is beer and isn't sweet at all so you can keep track of how much you drink better. One beer equals 1.5 ounces of the hard stuff and 5 ounces of wine.
After you party, the next morning you may not be able to stomach eating breakfast. Stick to something bland like saltine crackers. Saltine crackers will help settle any nausea you may be feeling and your stomach will thank you. Stay away from milk, too. If you need to drink something drink water. Coffee or pop is good also just take small sips at a time and only one or two cups or glasses. The caffeine will help revive you somewhat but caffeine is drying and you need to concentrate on hydration today.
If you have a beer hangover and need to take a pain reliever for your headache do yourself a favor and do not take the pills on an empty stomach. This is where those saltine crackers come in they will allow you to have something solid in your stomach so the medicine does not irritate your stomach. No sense in taking something that has the possibility of coming right back up.
After you have fixed yourself up with a couple of crackers and something to sip on, just go back to bed and sleep for a while longer. You will wake up feeling so much better. When you wake up the second time have some type of sports drink to replenish vital electrolytes you will have lost the night before. Not to mention the sugar will help bring your blood sugar up. If you do not have a sports drink on hand then just sip some more water.
You still probably do not have the energy to run a marathon or even just get from the bed to the couch so give yourself the rest of the day to just relax and take it easy. Order your meals in so you do not have to worry about cooking, if you even feel like eating. You could just heat up a can of soup to nurse your beer hangover back to health.
