I've taken it a few times when I really had to push hard to meet a deadline (coding). One time while working my sister texted me to say she just boarded her flight to Canada (from Europe). What seemed like a short while after she texted me saying she'd arrived. During her entire flight (6+ hrs) my concentration never flinched. I find it very effective indeed.
