Hi!
I have a book from my surgical team with specific instructions and I'm following those. Not everything works for me. I don't hesitate to call and tell them how I'm going to substitute, or change something.
As far as the scale, I'm not hung up on the numbers. I went out and bought a cheap manual version. Works fine! As many have suggested... forget the scale, measure, check your clothes size. It works for me!

Thanks on my way to the hospital now.
