Heidi,
Way to go and hope your husband follows your wonderful example!
By the way..if you are doing the treadmill for 60 minutes, that means you would be running in the neighborhood of 5-6 miles. If you want a guaranteed "high", start aiming for a marathon. I did 3! They were the Super Bowls of my life.
Anyway. Congratulations!
Scott
Day 32 and going double
