I also have Tinnitus. I got the ringing ears right when I started the blood pressure medication; Metoprolol I ordered a supplement called Synapse XT which I started taking, but after taking maybe for a week, I quit taking, because I came down with another health issue. It says to take two a day. I've been thinking about starting back on them. You mention taking a supplement for your ringing ears. What are you taking or did take, and how long did you take it before noticing it got better. Thank you in advance for any advice you may have.
