I felt like I was dying after the second cup in a day a few weeks ago. I didn't sleep all night, with pains in pretty much all my organs. A week later I tried another cup, a brithday gift to myself, and the same thing, although much less intense, happened again. So it looks like no more coffee for me. I've been drinking iced-water with a couple of slices of lemon, and this morning some flower tea.
