Cutting caffeine

I cut caffeine by 70-80% about 5 years ago and it has made a huge impact on my life. I have less anxiety, I sleep better, and I feel like I have a lot more energy. I still drink decaf espresso, green tea and low-caffeine teas sometimes, but only in the morning and not everyday. Once in a blue moon I’ll drink a Coke. I didn’t completely eliminate because I enjoy these things but I absolutely feel a difference for the better without constant caffeine.
