I read a book called 'panic away' by a person named joe barry?

I have not read the book, but I do know a bit about Generalised Anxiety Disorder. GAD manifests itself by a whole range of symptoms such as; palpitations, sweating, trembling, dry mouth, difficulty breathing, feeling of choking, chest pain, nausea, hot flushes, muscle tension, dizziness etc etc etc, the list is quite extensive. GAD is best treated with Cognitive Behavioural Therapy rather than medication, although a mixture of the both is usually done. Many people suffer from GAD for many years and this is why CBT can be the best treatment.
