You mentioned it’s not recommended for people who have not been using binaural beats for at least 3 months. What are some of the issues you might encounter  if you lack the experience?
hehe ;)
There isn't a clear line between "Beginner" and "Advanced" -- binaural beats affect everybody differently. Some people who try "Advanced" right away report headaches and nightmares, whereas others can jump right in without any problems. It's entirely up to you, I tend to be a bit more on the careful/paranoid side of things.
