Agree, the stress might have negated possible positive outcomes. In my case, though, I'm sticking with it purely for the joy of it--15 min. of HIIT at the end of the work while you are hungry and tired followed by a cold shower/bath for another 15 min. is like being knocked out and woken up after a long sleep--makes you relaxed and focused for the rest of the evening.
