Brainwave today released version 2.1 of its award-winning power napping and sleep software, pzizz. “The fast pace of the modern world, and a general feeling of uncertainty regarding world events, are causing problems such as stress and insomnia like never before,” says Edward Laing, CEO of Brainwave Enterprises and owner of pzizz. “Thousands of people from all over the world are finding that pzizz helps them to de-stress, re-energize and enjoy deep, restorative sleep –- at the press of a button!” Interestingly, the company says there are six new changes to the software, which they are not announcing. Instead, the first person to correctly list all six changes on the pzizz blog will win a new 4GB green iPod nano.
