Point taken. Reducing sugar is one thing. Reducing caffeine at the same time, and one will eclipse the other. With caffeine withdrawal being far more noticeable. It's why I continue to mitigate my caffeine intake, never drinking two cups of coffee two days in a row. Yesterday was coffee, today tea and tomorrow something without caffeine at all. Caffeine withdrawal can be nasty for me.
But I am glad you are on this journey. You'll find you don't need it as much as you think you do.
