Thumper is a stumper!
I really think Thumper has a sputtering pancreas, which is a great thing--but, it makes dosing decisions so difficult.
I think I would hold the dose and see where it lands you. I have found with Kitty, that if I hold the dose I get a much clearer picture. Even if the response is not what I want, the dose seems to settle in and the data becomes clearer.
Good Luck!
