My tinnitus has been really kicking up over the past few days. That's the so-called "ringing in the ears" that people can get. In my case it's a very high-pitched sound, not a pure tone, over a range of frequencies so high it's a combination of squeal and a hiss. Fortunately it's something I've been able to tolerate pretty well, only occasionally getting really annoying, as it has lately. I've decided to give ginkgo biloba a try; there have been some positive results reported with that. I've started taking 60 mg twice a day with meals for a total of 120 mg — what Dr. Weil recommends. If it doesn't work for the tinnitus, it's said to have other benefits so it hopefully won't be a total waste. We'll see how it goes!
