Just thought I'd share that I found a neat app that's available for my android phone and my Barnes & Noble Nook called Relax Melodies by Ipnosoft. There's a free version and a paid version. You have a ton of sounds to use to fall asleep to, do yoga to, even meditate. You can mix and match sounds, put them on a timer, it's really cool. I personally have been falling asleep a little faster when I use a combo of "Campfire" and "River". Love this thing!
No prob, anything to help! I was looking for something that wasn't just music as I concentrate on music too much to sleep, yet was more interesting than just white noise. The waterfall, hard rain, and wind work well too.
