re: Chest pains keeping me up

Your body is giving you a wake-up call. If you're over 40 there's a chance that you've got some artery blockage. If you're lucky it won't be in your main artery. If not, there's a reason they call that the widow maker. My brother died of a sudden heart attack at 57 but he had been experiencing symptoms for a long time and just ignored them.
See your doctor stat and don't downplay the symptoms.
