For nearly ten years now, I've been listening to my own orchestrations every night. A cocktail of music and brainwaves. And I've not had a cold to speak of. I've not missed a day of work in 10 years! I admit that I've had a couple 4 hour battles with feverish conditions, but with my regimen of rest, hydration and my mind music, I'm able to purge whatever is trying to attack my body in no time FLAT!
Can I guarantee the same for you? NO... But seriously, this is an inexpensive, mind altering expeerience that will save you a lot of money over your lifetime!
