Be Still My Heart

Last night was a little strange - well, really strange to be honest. In the middle of the night, my heart went through an episode of tachycardia for a few minutes. It was enough to wake me up from a sound sleep, and I know I didn't have a night terror. Or at least a night terror I remember, and those are things I can't forget. I just hope this is a not an indication of the way things are going to be on my vacation. I really need to rest and enjoy myself for a few weeks before getting back to work. Although it is possible all the work/overtime I've been putting in are a cause, but there are other things like vitamin deficiencies that can cause it as well.
