I’m fasting. B”H, I generally have an easy time going without food on fast days.
I have fasted every fast day since my Bar Mitzvah with one exception. On Asara B’Teves about three or four years ago, I came down with a fever. I left work early and went home. When I got home and saw I had a fever (which I already knew just by the way I felt — I know my body’s signs of a temperature higher than 100), I had a hot tea and toast. There was no way I was going to make it that day and so at about 1PM or so, I called it quits.
That is, to the best of my recollection, the only time since my Bar Mitzvah that I ate on a fast day.
