Fast Day 2: The Day of the Headache

Most of today has been consumed by a massive headache, despite drinking sufficient fluids (and caffeine, and salt). I'm down three plus pounds from yesterday, however I'm sure the three pounds (if not the plus) are from stored glycogen loss. I'm experiencing NO hunger, just a rollicking headache. I've just taken ibuprofen and I'm hoping it works. Otherwise, I'm soldiering on. This fasting thing seems to be absolutely no trouble at all as long as I don't have any sweetener. I've had a dash of cream in one of my coffees and it didn't stimulate hunger, so I'm guessing that what derailed me the other times I've engaged in fasting was the sweetener added to my coffee (Torani sugar free). Maybe the sweet stimulates enough of a cephalic insulin response that it gets my tummy ready for food.
