St Jude huh? Cool, I like them (so far)...

That is my scs brand...
Anyway, time off from work is dependent on what you do, sitting, standing, lifting, etc., as you will have some limitations and pain for a bit. When I got the "twins" implanted, I was cut in four areas and it was an overnight stay, I was out a total of a week and a half. I think I went back a little too soon.
When I had my leads replaced and battery moved, that was three incisions, and I opted to take an additional week and am thankful I did. I wasn't in quite as much pain as the first surgery, but I felt better going back to work after the extra week.
It is great that you will be able to do the self-programming. I will need to look into that like Mark56 says
