I don’t know why, but in some ways it’s easier to exercise…. Perhaps I’m adjusting to the routine…. Yet other ways, I ache all over and sweating. 
Oh, I ate yesterday…. But I drank lots of water too! I know not enough, but I drank more than I usually do. And I lost 4 pounds from my last weigh in. Portions are important & not eating late. Still I have to work on more water.
I have to keep my focus too: which do I want more, something momentary that really doesn’t satisfy, or a lasting reward?
