Have you suffered insomnia? I am a college student, I always feel upset under the hearvy burden of study. I can't go to sleep every night until the mid night. I am sad about this and go to my doctor. he introduce me about a free software which have a lot of music can help with sleep. So i try it every night, the music is magic,lol..., make me feel sleepy and go to deeply sleep until next morning. It named Brainwave Tuner, i love it and recommanded to my friends who have same problem as me. We all feel good.Just share my experience here, I hope Brainwave Tuner can help more and more people.
