Alue, it's gotten much better! Yesterday it was a bit too intrusive for my comfort level, but the prior 5 or 6 days it barely bothered me at all. Once in a while during the day if I left my work table and got up to do something, it would increase in volume a bit. However, my tinnitus is nowhere near the level as it was in the first couple years, and especially the first six to eight months were horrid.
It has taken a long time to get to this point, though. I started the ACRN and intermittent fasting in March 2016 and April 2016, respectively. I don't think it's habituation, because nothing changed very much before then. After the first 6 to 8 months in 2014, it had remained fairly constant at a 7 to 8 out of 10, and occasionally dropping lower than that. The ACRN gave me the first signs of true improvement.
I understand a little about anhedonia. I think maybe you do have the emotions but they're blunted and not rising to a conscious level. Just from my point of view, the emotions that still come through in your posts are apprehension and frustration. So you could say, "I hear the tinnitus and I feel apprehensive." I always add why I feel what I feel. For example, "I hear my tinnitus and I feel annoyed because I want to enjoy this walk with my dog." Maybe you could say, "I hear my tinnitus and I feel frustrated because I want to concentrate on my work." I think that makes the prefrontal cortex a bit more involved in the process.
The Back to Silence method can take a long time if your limbic system has become too "attached" to your tinnitus, but I found that if I stick with it, it does make a bit of difference.
I hope this helps.
