Patients will be randomized to one of two study groups. They will then be asked to rate their pain and nausea on a line graph. If the patient is a female of child bearing age, a urine pregnancy test will be done per standard of care. After this, an IV catheter will be placed in a vein in the patients arm. Pain medicine will be given through this IV per the doctor's order. With this medicine, patients will be given 10 milliliters (2 teaspoons) of either Sodium Chloride (salt water) or Phenergan mixed with Sodium Chloride (salt water). Phenergan is a medication typically used to help with nausea and is a common ingredient in prescription cough medicine.
