So, pacing yourself and limiting yourself to one drink an hour are ways to keep headaches and stomach upset at bay. Most likely, the alcohol and the lactic acid that builds up as the alcohol is metabolized are responsible for the nausea, headache, and irritability. These symptoms, as well as thirst, are also a result of alcohol's diuretic effect, increasing one's need to pee. When drinking alcoholic beverages, you will wind up letting go of more liquid than you take in. If you wind up feeling sick, despite precautionary measures, there are a few things you can do.
Some people take aspirin, acetaminophen, or ibuprofen before going to bed or upon waking.
These may help to relieve headache and other aches and pains, but they do not decrease the amount of alcohol still in your body, so you will still have other hangover symptoms. Aspirin can be a stomach irritant, as can ibuprofen. Since alcohol can also upset your stomach, mixing the two may cause ulcers, gastrointestinal bleeding, or other sensitive-stomach symptoms. Also, mixing acetaminophen with alcohol has been linked with liver disorder, and even failure, in some people, even when taken in normal doses. Always consult with a health care provider if you take any medications and consume alcohol.
