I have been feeding him better foods. I fuss at him for drinking Pepsi, and he has cut way back. He does drink a lot of water during the day since he works outside. He just doesn't see things my way all the time. He tolerates the extra money I spend for supplements and vitamins and organic foods, so I don't want to push it. He will take supplements and eat better, but a cleanse would be pushing it. I have told him these things, but I'm not gonna be a nag. Thanks for your response.
