Thanks all. Im back home now. Imaging/stress tests/etc came back good.
It seems one of my blood pressure medicines had lowered my potassium so that was giving me palpitations and some chest pains and on top of that it could also have been a case of acid reflux.
The hour after they gave me two cups of the potassium supplement I felt like a million years.
So tomorrow Im going to my primary phys and seeing what I can do to get that med changed. ive been taking it for years and its been years that ive been feeling tired and had no clue it was low potassium.
Gald to hear it. Add some bananas to your diet, most people like them, and they're loaded in potassium.
For the time being im eating two bananas a day 
Ahh, I see you're already there. Also, they sell potassium vitamins/supplements that aren't too expensive (great to keep around too, for mussle cramps. Wake up with a charlie horse, drink a glass of water and take 2-3 of them, you won't have another cramp all night).
