Thanks for your words! I am very happy that you achieved such a far-reaching habituation. I hope this will happen to me, too. Not having to think about and hear my tinnitus for 90% of the day would be a VERY big relief compared to how I feel today. I would be VERY happy with it.Of course! It definitely was gradual for me. I remember last summer, I was getting back into Skyrim, and I could hardly focus on the game because of how much I was actively listening to and checking on my tinnitus. The stretches of time where I wouldn't think about it or "hear it" were very small at first, but they did gradually increase. It wasn't linear, though; I had many setbacks while I was habituating, which is normal (but upsetting). If you can forget about it for a minute, 5 minutes, 10, then that shows your brain is capable of tuning it out to some degree and that eventually you will be able to go even longer stretches of time. That's what I would try to tell myself when I was really anxious and caught myself monitoring it.
I cannot stress enough how much of it really is just the passage of time and kind of a waiting game. It's slow, and it's painful. As I mentioned, I had many setbacks during my first year because my tinnitus would worsen/add new ones every three months. Every time I thought it couldn't get worse, it did. But now I'm relatively okay with my tinnitus. I still have my moments - I'm listening to the orchestra of sounds and distortions as I type this. I'm a bit anxious about it. But I know in a little while, I will stop actively listening to it again and be okay. I didn't think I would ever get to this point. I have autism, OCD, and a large collection of other disorders. I thought I could never adapt to life with tinnitus, not because I think my tinnitus is worse than everyone else's, but because of how my brain functions (and/or doesn't function). Tinnitus is a sensory nightmare, and my autism and OCD have had a field day with it. But I have adapted to it with time. I still think about it sometimes and hear it periodically throughout the day, but 90% of the time, I don't. I try to take that as a win!
I hope that habituation won't be the best option in the near future. I hope we can have a cure for tinnitus, or at least a way to significantly reduce the sound levels and suffering that come with it.
But for now, hang in there and stick with it! Distract yourself, play some soothing sounds to help you sleep, and do things you enjoy despite having tinnitus. If I can do it with my extremely disordered brain, I believe you can
What I can say, however, is that I have days (and more and more often?) when the noise doesn't bother me as much, seems less intrusive, and is more easily overshadowed by ambient noise, so I don't hear it.
