Is there a real way to completely eliminate panic attacks?

Depends upon illness: As in other areas of medicine, there are many variables.The reality of "the anxiety disease", a book by dr. David sheehan that i recommend you read, is that when it comes to panic disorder there are often relapses in spite of the best efforts, including cbt, relaxation therapy and meds.Cure is not the best word to use. Treatment to diminish them and manage them are more appropriate terms to use.
