We've gone through a lot of treatments, none of which have worked, and have spent a lot of money on doctors, none of which has actually helped. Which is one reason I find the ads for a particular substance (I'm not going to help their marketing further by naming it) on the radio that claims to cure tinnitus to be so annoying. No, we haven't tried it, and we're not going to do so. Lisa was the one who first noticed the ads and complained at me about the people preying on desperate people such as her. For a longer, better-developed take on the subject, I recommend this article by Dr. Marsha Johnson, who has recently been trying to treat Lisa's tinnitus.
If those substances really work, the promoters should submit them to proper clinical trials -- if it's anything other than the placebo effect, the inventor will make a lot more money than selling it snake-oil fashion over the radio. Unless it is snake oil, of course.
