two years i had my first panic attack after a night of heavy intoxication with a bunch of friends. at the time i was a very very overweight heavy smoker and drinker. i lived an extremely unhealthy lifestyle. over the next year it got extremely worse, i started going to sleep every night with an extremely heavy head, facial tingling dizziness, hearing my heart thumping in my chest, chronic heartburn, trouble breathing, tinnitus, sweating feeling sick etc.
