I do feel so weak, and my arms are trembling. I walk and have some feeling of dizziness, again today. I still feel like I'm lighter than air, like my head makes me a balloon with a string coming out the bottom, though the bottom feels like a ballooned fun house thing. I can't like hold still easily, neither. Sometimes, it causes me to tremble ... tremble ... tremble. Well, I can help it a lot, too.
