First of all Annie, let me say WHEW! I'm so glad the kidney problem was a human error problem! I was really worried out you.

Secondly, thank you for the post. It was very clear and concise, except I think I missed was the PVC stands for. Can you elaborate, please? I re-read and still couldn't figure it out...... Like I always say - I'm Old (even older than you - HA!).

Giant High 5, and lots 'o hugs to you!
