Wonderfully detailed post! I didn't experience the cold thing, and I'm still struggling with heat intolerance. It got up to 95 today, and it's been so hard to make myself get out of the house and into my hot car. Ugh.
The hunger thing varies person to person. I had your experience in the early days and my appetite and hunger have returned just enough to ensure I eat, and even enjoy what I'm eating, but not enough to change the fact that I'm full after 2-3 tablespoons and want no more. That's a good place to be for me.
One more thing, I slept with a king size pillow over my stomach due to furballs, and it's been a life-saver while healing. 4 weeks out, I can tolerate being jumped on once more.
