Congratulations in that you have things going in the right direction!! That is the hard part.
As far as noticeable changes, I bet you are standing just a little taller, and your eyes have a new flicker in them that will turn into a full sparkle as your success grows.
As far as Taco Bell, just make a new decision for yourself right now...not tomorrow...but with every new moment. The past is not worth punishing yourself over. Only look back to learn something that could help you today. I'm not really good at that either, but that is my goal.
