It is best to eat a light meal before your appointment so that your body has energy to work with. Sometimes a person who has not eaten will feel lightheaded or weak when receiving an acupuncture treatment. In this case, inform your practitioner immediately and they will take the appropriate actions. It is best to wear shorts or loose clothing so that the arms and legs below the elbows and knees, as well as the abdomen, are accessible. Do not engage in strenuous activity, drink alcohol, smoke excessively, or ingest heavy meals before or after your treatment. This will allow the body to adjust to the effects of the acupuncture.
