Squeeze the grapefruits, oranges, and lemons separately and do not mix the juices at first. You will need 1/2 cup of grapefruit juice, 1/4 cup of orange juice, and 1/4 cup of lemon juice. Mix them together well, then split the mixture up into separate glasses, each filled with 1/4 cup of juice. You will also need 1 cup of olive oil separated into four doses of ¼ cup each. Wait until about an hour before you plan to go to bed. Take 1/4 cup of the citrus mixture, followed by 1/4 cup of extra virgin olive oil.
