Well for instance, I only drink water now. No sugar drinks or anything like that. So is drinking water only, really a "replacement"? I reduced and stopped doing others things, and had to drink water... cause... you have to.... LOL. But I didn't replace one type of drink for another. I also stopped smoking, and didn't replace with a habit, just decided to stop with will power. It's a higher vs. lower consciousness dichotomy. We either don't engage in our higher consciousness power to override conditioning, or we do engage in that power and change our lives!
