We're happy to hear that you were satisfied with the Cleanse and recommended your husband to do it.  He can adjust the intake of the capsules according to his personal schedule. If he works overnight and is asleep during the day, he can start the regimen when he is up. He should just be sure that he's consuming the formula's every 2-3 hours as instructed.   There are raw foods that helps naturally provide the body with more energy, but they're not the same as consuming caffeinated beverages that would keep him up.  Most raw foods just have multiple benefits.  The Cleanse also helps improve your sleep.
