Oh and I meant to say, I was tired as could be when I started eating again, for a while, but it did pass and energy replaced it in waves. I might be tired 5 days in a week and energetic 2, a couple weeks later I might be tired 3 days that week and energetic 4. At this point, a tired day has become a rarity and I mostly have energy as long as I get my sleep. I took a crapton of naps in the beginning.
