caverna, try and break it down into hours or minutes if you have too. There are days when that's the only way I get thru it, one more hour, one more chore, one more sink of dishes.... whatever it is that keeps me from doing something I'm trying to keep myself from doing. So if you're trying not to call, instead of saying one more day, say one more hour, or one more tv show, or one more trip to get a glass of water. Breaking it down in to little pieces might make it easier little goals.
