For me it's all in the timing. The main problem I have really these days is with my balance still and that seems to be worse when I don't sleep. If I have a sleepless night I'm extremely careful how adventurous I get that day. I might feel ok to head out for a walk or go to the shops but that can all change in an instant.

So timing is important I think. I work, walk, garden etc when I feel good and I don't when I don't feel quite right.
