I clench my jaw day and night, like constantly. Not intentionally, and I wear a mouthguard to protect my teeth at night, but I'm not really in control of the clenching and it causes downstream effects. Some mornings I can't open my jaw all the way. I had the feeling of water trapped in my ear (I thought it was from using the pool at the gym), but the ENT told me it was from TMJ. At least a couple times a week I end up with a headache that starts in my jaw and teeth, radiates up my sinuses, and on really bad days, results in light sensitivity and blurred vision.
Sorry if this is too personal, but I've heard magnesium can cause diarrhea. Does that happen to you? Also, what kind of magnesium do you take, and is your bruxism related to anxiety?
I've heard magnesium oxide is the most diarrheic and least effective otherwise, so I avoid that. I take magnesium citrate, carbonate, hydroxide, acetate, malate, bisglycinate, taurate, gluconate, or whatever combination of them happens to be cheap. Never tried threonate because it's so expensive.
There was even more anxiety with caffeine, so yeah, related.
