A few months ago something weird started happening with my heart: flutters that freaked me out. They would just last for a second but it would send my body into shock -- I'd be a little lightheaded and cold and would have a hard time concentrating. This was no good at work. And when it happened at night it would wake me up full of adrenaline and a disconcerted feeling. I'd wonder "should I go to the emergency room right now, is my heart about to stop?"
But the answer is no, this just happens to some people. (According to my new naturopath.) In fact it happened to my Dad as well, and he fixed it by jogging 10 miles/week. So I'm doing that, and also cutting out caffeine, and also drinking emergen-C to rebalance my electrolytes. (The heart is a muscle, and bad electrolyte levels along with other body stress can make muscles twitchy or something.)
Living without caffeine is HORRIBLE! And my legs are sore all the time from running. (I'm restarting the
Bag End to Rivendell challenge. At the end of week 3 I've gone 30 miles, so I'll be facing a Nazgul on Monday.) "Tired + sore" really takes the sting out of the prospect of an exploded heart.
I was running a 12-minute mile when I started but now it is 10 minutes/mile. I did 9 once last week (for 2.5 miles) but it wasn't much fun so I'll stick with 10. For some reason running outside is much easier than on the treadmill. So I hope it doesn't rain in Seattle this winter.
