I stopped drinking completely. The positive effects are worth it in my case: I feel calmer and I have energy for the whole day without ups and downs. Imagine the state you are after drinking coffee. That’s my normal state now. Caffeine seems to give a high feeling but it seems to be just a feeling because of the stress reaction. It doesn’t help me at all with mental tasks. YMMV, that‘s just my Impression.

My body even reacts to a glass of Coke with an increased heart rate now. So I’ve cut back on caffeine nearly completely. I may drink an espresso now and then in future after a meal. But I will definitely not go back to drink coffee habitually.
