For me...it's important to get sleep and I have felt a lot better generally once I got back to a regular sleep pattern.
However...on a DAILY basis...I usually feel WORSE after sleeping. I think it's because of the immobilization for such an extended period of time. Whatever the reason...I'm usually in more pain and have more swelling after I sleep and it's really hard to get moving again.
How's that for a complicated answer...
