 So, change is actually very difficult. There's been some really good studies that suggest that a new habit takes about six weeks to form. And I tell patients that for a couple of weeks you get to hate me, because I'm changing a lot of ingrained habits. But the interesting thing is that after about two weeks, people actually start liking me because they feel so much better. And one of my patients early on, when I asked him how he was doing, he said, you know, feeling well never tasted so good. And the feelings you're going to get by following this is usually so remarkable that most people want to stick with it. The less you cheat, the easier it is. But make sure you understand that it's going to take about six weeks to ingrain a new habit. And less cheating, better long-term success.
