I think that T volume waxes and wanes with neurochemistry and hormones which are on a cirdadian cycle, and has little to do with how much attention you devote to it (though ignoring it is a great thing to do when you can).
Hi mick,
Just want to add I concur! I know there's a neurological hormone or chemical connection that alternates as part of your body's rhythms. The 24-hour circadian cycle is part of it; but there's more at play. Recently, I was thinking how could our physicians' test this? Perhaps, it's as simple as a blood test; we need only to know what to look for. I do know melatonin helps most tinnitus suffers, myself included. And melatonin acts on your sleep cycle.
Besides the melatonin connection, I had an incident that reinforced my belief in a chemical cycling. Several months ago, I was lying in bed around 3:30 am listening to my tinnitus--which was being particularly obnoxious. In the course of a few minutes, the tinnitus slowed down. Then it abruptly stopped. No sound. Within 15 or 20 minutes, it resumed, but the volume had diminished significantly. My brain may go through this nightly, for I always wake up with low tinnitus--even if I'm going to spike a few hours later.
Besides a 24 hour cycle, my tinnitus has its own rhythm that is not predictable. I know if I eat something with MSG, for example, I'll have a bad day or two. But I can do everything right: eat properly, exercise, sleep well, and be very, very happy--and I'll still spike! I've never gone for more than three days without a spike. And the spikes usually last a day or two. Sometimes three. There's no pattern I can discern, yet there must be pattern chemically.
To anyone still worried about antidepressants: Don't. Antidepressants act on the limbic system, which is key to tinnitus distress, so it's only natural you'll get relief. (Relief of misery, but not necessarily of sound.) As Markku notes, if the antidepressants do increase the noise, it's usually temporary. And if the tinnitus doesn't return to baseline, you can always try a different class of antidepressants. These drugs in general are very safe. You shouldn't combine antidepressants with melatonin unless your physician says it's okay (melatonin is connected with serotonin), but most antidepressants also relieve anxiety and so help you sleep anyway!
