Good for you! I am also restarting my health goals, and I am doing well this year, too. I think the difference for me is also about reorganizing my goals. Instead of the goal of losing 50lbs, I am focusing on losing 4 lb, in one month. Much more attainable.
I also use this site every day. I try for SparkPoints. This makes me read articles, blogs, recipes. I take the quiz, trivia and polls. Because all this extra info is really making me so much more aware of my total health.
I was also addicted to Diet Coke and I am so glad I am off it. The chemical cocktail is so bad for humans, and it is intended to create addiction. And insulin resistance. I am now a type 2 diabetic, and I am certain that if I had not been drinking diet coke, I may have not got diabetes. Dang.
Good luck to you in your journey. You are doing a great job!
