welcome to the board.
You sure are looking after yourself well and i would think that if your diet and exercise are as you say then the chest pains are most likely from anxiety and maybe pushing yourself too hard. Are you actually a firefighter(like your signature says) as i'm sure that's a fairly high stress job.
If you didn't start drinking till you were in college that may well have been a trigger. They can also be family related, inherited i mean, wheter it's geneic or learned behaviour i wouldn't know.
I know you say you only drink alcohol occasionallly but when you do are you getting drunk, as this will definately be the cause of paranoia, sickness and feeling out of control. Maybe consider giving the alcohol a miss for a few weeks or months and see if it helps. If anyone asks just say it makes you too sick in the morning.
As a person who started drinking at 13 and was an binge alcoholic by 19 it's a road best avoided. I think i made myself intolerant to it, even a glass of wine would send me loopers now.
Take care and try to find something you can relax into, sport is great, gets the adrenaline pumping, but maybe you also need something to unwind too. A gentle walk on the park, a good book, music etc,,whatever does it for you.
My thoughts are with you, boo
It is nice to get to know you. Some of my favorite people of firefighters and EMS personnel.
You could try a benzodiazapine such as Xanax on an as needed bases or Buspar(Bu Spar) which is a traditional anxiolytic. I use the Buspar daily and it really has helped me. I do have Valium to use if something gets way out of whack. Please do discuss meds with your physician and then make an informed decision on what you feel meets your needs.
I would give up the alcohol and see how much better you feel.
Again welcome to our world.
