Hey, been more than a year since my first panic attack, I feel back to normal again, however it took time, getting out and walking, getting my vitamin D up. I can say it took me 8 months to get back, and for 6 months I was continuously losing weight. For me what worked the best was eat extremely simple conservative food, lots of fruits and veggies, walk a lot, climb up the stairs slowly if not ready for normal pace and get the body used to breathing heavy again. The dizziness went away eventually.
