Should I do D of E for medicine?

When most people started doing D of E I unfortunately was very ill and so could not participate. However now I'm better, I have decided to pursue medicine as a career. I have thought bronze and silver D of E would be a good award to do as it is apparently fun and would be a good extra curricular to put down, however it would mean starting to play an instrument or something as I only have one extra-curricular currently and that is exercise? Is it worth all the hassle? (from someone who's completed it?) And is it too stressful what with GCSE's and A level choices coming up?
