I did a slightly better job getting to bed last night: 1am instead of 3am. The fitness band says I got a good chunk of deep sleep.
Woke to five fewer pounds, 453 (rounding up/down to the nearest pound.) Blood sugars up a bit from yesterday, just a couple of points. Energy levels have been good overall.
Just plowing on. I still have that empty feeling, but am not hungry. A bit of chilly hands, and a bit of muscle fatigue, but less than the last fast so far.
Now in Day 4. Taking it a day at a time.
