Many people believe (incorrectly) that it is a good idea to have a few drinks before getting a piercing or tattoo, and that it will lessen the pain felt. While having a few drinks can indeed numb out some of the discomfort associated with tattoos or body piercings, alcohol also thins the blood and can lead to excessive bleeding, or loss of consciousness.
Professional body artists know that mixing alcohol and getting a tattoo or piercing are not a good idea, and will usually refuse to work on a client that is obviously drunk. Instead of having a few drinks to ease the pain, a better solution would be to take an over-the-counter pain reliever called acetaminophen (the active ingredient in Tylenol). Acetaminophen will help lower the pain you will feel without thinning your blood. Remember, whether you are getting a body piercing or a tattoo, make sure you consult the services of a professional body artist that is in full compliance with health department rules and regulations and who uses the proper body piercing supplies for the job.
