The Linden Method Approach
The Linden Method is another alternative treatment I experimented with when I was suffering from my panic attacks from insomnia.
Charles Linden from the UK designed the program, and it certainly had a more scientific approach. Essentially there is a prt of the brain called the Amygdala, which is responsible for anxiety. If you can learn to control this part of your brain, you can control anxiety and panic attacks.
I have done research on this as an panic attack treatment, and it seems there are many satisfied customers. I personally felt that Panic Away was a easier to follow approach.
