Its so good to share our cleansing journies on this site. As you know nagging is a waste of time. One thing you might do is schedule a liver cleanse and tell him that he needs to join you just for the adventure of it, so that you can compare notes. Pour the oil and the lemon and hand it to him. You might tell him that you have planned a surprise when you are done (for the next day, of course). Of course he will have to skip dinner that day, but think of something that will help him to forgo a meal. Remember how kids get what they want, they take it for granted that they will get what they want. Good luck, Giz :-)
