>the other two types always go away after good sleep
In other words, it seems the other two types of tinnitus are sensitive to the amount of reactive oxygen species (ROS).
When you sleep, the ROS are suppressed by glutathione. Then, you feel fresh and rested when you wake up.
When you go through your day, the amount of ROS slowly but steadily increases until you sleep and allow glutathione to do its job again. The cycle repeats.
Given that your tinnitus seems to depend on ROS, I would suggest to experiment with NAC 600 mg and see whether it improves the symptoms. NAC is a glutathione precursor and causes the immediate suppression of ROS.
If there is a correlation then the condition can be treated and improved.
Is there a medical specialist that one can go talk to about this approach? I am open to trying it, but would rather do so using someone with a medical license versus Internet wisdom
This is pretty new area so chances that you will be able to find a corresponding specialist around the corner are dim. Probably the closest matches are nutritional neurologists and holistic doctors.
There are some public materials by people like Elliot Overton and Sten Ekberg. As far as I know, they do general practices combined with private consulting as well. You can try to reach them remotely or physically by visiting their clinics.
