Had a similar situation back in my trucking days (early to mid 30s) but not as severe. Made the mistake of telling my wife, mostly due to the fact that my older brother had just had a pretty severe heart attack. The symptoms he described were similar to what I was feeling. My wife immediately scheduled a stress test. Came through with flying colors. Doc asked about my diet. When I told him he just shook his head and said, "You had a bad case of indigestion." Calling Starvin Marvin hot dogs, tater chips, and twinkies washed down with copious amounts of strong black coffee, along with a few ephidrine pills a "balanced diet" will do that for you.
