Do you mean it made tinnitus worse or sleep worse? I take a different z-drug called zolpidem (Ambien), but my sleep problem is usually waking up in the middle of the night and not getting back to sleep, so I usually wait until 2:30AM to 4AM timeframe, and take a small dose ~2 mg sublingual many nights. It helps to get me back to sleep and is still effective over 16+ months. No effect on tinnitus.

But despite that, I'm still not able to get enough sleep. Some people take antidepressants Trazodone, Mirtazapine, Doxepin, or Amitriptyline to help with sleep.
@RunningMan thanks for your reply! I meant worsening of tinnitus specifically. I feel my tone has become louder but perhaps would have happened without meds too. Zopiclone also only makes me sleep 3-4 full hours so dont take them anymore. Good to hear zolpidem is helping you with no effect on T!
