Hey Bob,
Thanks for the update--this is fantastic news! So you really were full of ... I had a feeling.
From one 2-level to another: take things slow and enjoy your time in Germany. I actually walked about 4.5 miles at 10 days post-op (doing a lot of sightseeing), but I was in no pain other than the surgery induced pain / incision site. Going to Germany/Austria was one of the best "vacations" I've had--surgery was icing on the cake!
Keep us posted and be well my friend.
