question: Hello, my husband just told me he has for the past week he has been feeling a excitable feeling in the chest as if he is on a roller coaster. He says it doesnt hurt and that it feels that it takes a lil bit of your breath away like when your coming down from a roller coaster. He is diabetic but has been off metformin because his Dr. said that he was doing so well that he could get off the medication. My husband is a truck driver and doesnt sleep a whole lot maybe 5 or 6 hours.My husband is 48 maybe 170lb 58
