The Serene Escape Portable White Noise Machine is an extremely viable option as an alternative sleep aid. Using different sounds, as opposed to chemicals to aid you in resting, makes this a safer solution as well. Offering 6 channels with 6 programs each, you have 36 different sounds to choose from.  With volume settings, a timer & a lock to prevent settings from changing during travel, this wonderful, portable, USB-charged device may just be a dream come true (sorry, couldn't help it!) for you and your resting problems!
