I decided to give it a shot, to see if I really needed the air filter machine in my room to use as a masker for my tinnitus. Being that I've been able to sleep in hotel rooms without this stuff, I should be able to sleep at home too. Sure enough, sleeping was not an issue! Actually, sleeping never was... but when I wake up, I notice my tinnitus is reduced. It does slowly come back during the day, but it seems to almost be gone.... though there are still times it spikes depending on situations I am in. This leads me to believe that my tinnitus is either related to my dental work still which I've been trying to get fixed or related to some liver issues.
