I wrote about this in someone else's thread, but I also had balance improvement -- however, it was "head" balance stuff, not core trunk balance, if you know what I mean. So vertigo-related stuff improved -- I was able to look left and right without feeling dizzy-sick, for instance. But if I lean over too far while sitting I will still . . . slowly . . . go . . . down.
I guess that's strength, not balance?
Congratulations. I am so happy for you. Stay hydrated!
