I had been wondering how all of this was going after our lunch. Definitely send up the fan signal if there's ways you need help, and as minim said, two pounds is not significant of a change even in a day, I wouldn't worry about that.

Also, mr. sdw's mom and aunt both had/have multiple myeloma (his aunt has had it for several years now), so if it does turn out that way and you'd like some direct experience, please reach out. Sending hugs and love.
