I have it 24/7, nothing seems to help. It can be only masked by external noise. Alcohol doesn't help me to get temporal relief - it's even worse, louder.

But by far the worst consequence of tinnitus and the real problem (at least for me) is disturbance of sleep. At first I couldn't fall asleep - because of the noise which manifests itself most strongly in silent environment. So I was lying in bed for a few hours before falling asleep (now I got accustomed so I can fall asleep faster). But even worse is that the noise wakes me up after like 4-5 hours. That means I'm completely exhausted all day, because I need 7-8 hours of sleep to feel refreshed. I tried Zolpidem, which can get me 6 hours of sleep, but its effect wears off rapidly if taken for a few consecutive nights. Now I take Mirtazapine, which works better. Also it helped me to take Magnesium supplements.
