Yes. Yes. As the morning has gone on, I found my energy level building and building. I'm doing stuff I never do by choice. I work out of my basement and took a break to vacuum the whole basement, took out the trash (just to get some fresh air). I just realized it's 1:30PM and haven't eaten a thing all day and I'm not even hungry.
Changes yes. Subtle, no! I feel like wistling while I work. It's great to be back amongst the living. I feel 20 years of ill health beginning to melt.
