Sleep can be hard to come by. Stress at work, money issues, regular late night partying, the flight attendant you met in Dallas - can all contribute to poor quality sleep. If you can get any sleep at all. And you don't need to read reams of mind-numbing scientific studies to know that lack of sleep can have a negative effect on your health and performance.

Fortunately for us there are researchers (the ones not looking for new ways to give us longer lasting hard-ons), who've found that certain stimuli can effect our brainwaves, helping us relax more thoroughly and sleep better.

How can you access this stimuli without having to head to a lab every time you need a nap? Use a program like Pzizz.

Pzizz is a downloadable software program that pulls from three types of files - words, music and sound effects - that were all specifically created to stimulate your subconscious and get your brain to move into the state where it can get the rest it needs. (It's way more in-depth than that, but let's face it, neither one of us would understand it anyway.)

Unlike typical relaxation CDs that play the same tracks over and over, Pzizz takes their files and mixes them together to create a different soundtrack every time you hit the play button. Over 100 billion possible combinations. Which keeps it from getting stale and repetitive. It's like having an endless library of soundtracks for under $50. (Plus Pzizz gives you free upgrades forever.)

They've got two different modules: Sleep, to get you into a deep, calm slumber, and Energizer for a quick nap that'll help clear your mind, get rid of stress and get you focused for the rest of the day. Each module can be customized for length, so your nap can run ten minutes or twenty minutes, depending on how long you can keep people out of your office. And since you can export soundtracks to your iPod, I use the Energizer when I fly to keep me rested and focused when I land. Especially if I'm meeting the flight attendant for drinks later.

$29.95 - Sleep or Energizer each individual module
$49.95 - Pzizz Bundle containing both modules
