While many want to know how to not throw up when drinking, it is in fact better to throw up if you are feeling nauseous after drinking. Nausea and vomiting are often signs that your body has more alcohol than it can effectively process. Therefore, while throwing up doesn’t feel great, it may be helpful to get rid of the excess alcohol or acid buildup by letting it out rather than forcefully holding it in. However, avoid forceful vomiting.
