You were right. I should have read all of his posts before saying that we don't need to encourage him to stop posting for a while. I still think that the best response is the "broken record" response... just keep reminding him that the 1st step to healing is through the desire to heal and taking the step of changing his diet. I can see how the MULTIPLE posts and the frequent asking for help and then being unwilling to really hear others' advice can be both frustrating and unproductive.
Hats off to everyone one on this forum who has tried to help him!
