Aside from the much needed energy boost after I was diagnosed (I was falling asleep at work at 2 pm - after 3 Red Bulls), I also found that I had a much more positive attitude to working out. I have always been an athlete, but my moods went from negative/shakey/lathargic to actually feeling the need to get in shape. I still have days where I could take a pass on hitting the gym, but it's been over a year and I almost feel bad if I don't go.
