+1, these "waves" used to happen to me all the time, I know exactly what you mean. The tingling sensation, the dread, the increased heart-rate, the nausea and dizziness, the itchy heat, i understand it. after about 6 months or so I was just so used to having these waves of panic attacks that I was somewhat able to control them a little bit.
After a while, even while you're in the psychological trap during an anxiety attack, thinking there's something wrong with you, you can grasp the fact that there's nothing wrong with you and that you're just having an anxiety attack.
Knowing there's nothing wrong with me has helped me infinite times when on the verge of insanity.
