does this permanently cure insomnia or do you have to listen to it get results every time
Binaural beats don't really "cure" anything. However, I used to have the world's worst insomnia whereas now I usually go to sleep right away. By using binaural beats repeatedly for years, it became "normal" for me to fall asleep quickly, to the point where I don't need them to fall asleep any more.
