I don't have anything I can point to. I also struggled to give up caffeine on my first couple tries. On my last attempt, I noticed that I stopped getting migraines, which gave me all the motivation I needed to stick with it. I only have a sample size of myself, so my advice may not be worth much, and it's definitely a cliche. What seems to work for me is to set a modest goal and don't get discouraged when I don't meet that goal the first time. Once I hit that goal, I stretch to something more ambitious. Sometimes you'll find you have goals that you don't really care about as much as you think. It's okay to set them aside and pursue the things that matter to you. Okay that's it for unwanted-advice time. :) Good luck with your goals!
