I don't need it - I had my first cup of tea at 3:00 yesterday and first coffee at 4:30. I do like one cup a day, usually after I've been up about an hour. I have been drinking it with butter and coconut oil. The rest of the day, I switch to plain tea - Barry's Irish tea.
For years, I couldn't drink coffee - it threw my heart in atrial fibrillation, so I enjoy my one cup a day now.
