I don't drink alcohol at all and haven't for quite awhile, and my blood pressure is pretty low and hasn't changed significantly. I did try cutting out caffeine entirely for several months (and the tinnitus actually started when I wasn't haven't any caffeine at all).
I do very slightly grind my teeth in my sleep, but in this particular case the problem is basically solved (at least at the dental level) because I have mild sleep apnea so I sleep with a plastic mouthpiece every night anyway.
I'll look into the magnesium supplements.
Yeah, caffeine is not the cause per se - the thing is it has both vasoconstriction and vasodilation effects at different times, so it can mess with blood vessels in the inner ear. It totally makes sense if you get tinnitus when you cut caffeine after your body is used to it.
Magnesium plays a part on vasodilation regulation as well, and many people are silently deficient on it. It’s hard to detect deficiency w/ blood samples, because the body works hard to keep blood concentration stable. You will know you do if you get muscle cramps or twitches.
