Jexa, I read (and tried) that if you eat something right before bed like an apple or bagel the teeth clenching and grinding will ease because you'll "exercise" your jaw with that and it will want to relax. The thing I read (might have been in Potatoes Not Prozac?) said clenching/grinding is like your brain twiddling it's thumbs and if you give your jaws something to do then the twiddling can't happen because your twiddlers will be worn out I tried it once or twice but slept through any improvements so don't know if it works.
