You will need to obtain one, 3 ounce bottle of Fleet Phospho-soda saline laxative (Ginger-Lemon Flavor or Unflavored) available at most pharmacies. If a larger size is purchased, do not exceed the recommended 3 ounce dosage given in the instructions, as serious side effects may occur.   Individual responses to laxatives vary:  this prep may cause multiple bowel movements.  It often works within 30 minutes although it may take as long as 3 hours.  Please remain within easy reach of toilet facilities.
