Thanks all for your replies and support. Cecilia, I have been back to work part-time for a little while. I still have several docs to see (internist, GI, nephrologist, pain doc for my sciatica and dentist-3 root canals, 2 down 1 to go!) so my calendar has really filled up. But, I'm loving it. I feel like I have rejoined the human race. I do get pretty tired by the end of the day though. Thanks for asking.
