hello, I am a 28 year old muscular male. I am the owner of a successful plumbing company and work a lot. I also smoke about a pack a day and drink 5 or so drinks 3 or 4 times a week. I have been not feeling good for about 2 years now. I almost fainted on a jobsite last year and took an ambulance to the hospital. The emergency room diagnoses was a panic attack. I was skeptical but I keep feeling like something is very wrong and I am going to faint, but I never do. I dump cold water on my head and wait for it to pass, sometimes it takes hours where I feel I am having a heart attack and going to faint. I have had an ekg, a ultrasound of my veins, and a heart stress test, all came back fine. So I have accepted it as panic attacks. I know I need to quit smoking but have been unsuccessful, are there certain things I can eat to help this..if so what? What about the headaches and chest pain? Thank you
