Clenching jaw...?

I'm on day 13 and have recently noticed that I have to "remind" myself to loosen up my jaw muscles...especially later in the evening and when I'm going to sleep at night. This has happened during some previous cleanses as well. I don't grind, but I often find that my jaw is clenched. I'm generally a relaxed person by nature...I don't have any additional stress in my life at the moment, nor do I ever really. I exercise outdoors often, live near the beach and canyons, don't work too much, and have plenty of down time to read, relax, play with the dog, etc. Though I have always found (cleansing or not) that I clench my fists constantly (driving, writing, holding the dog leash, etc.). I was just curious if anybody has any thoughts on this ~ or is this just one of my cute (HA!) little quirks? Tweet
