I use the Hearos concert earplugs every time I go to the movies or attend a loud event. I can still hear the dialogue, but during loud moments I'm not overwhelmed by the noise. I also use earplugs whenever I'll be in a noisy environment, like a busy city street or sidewalk.
I know some people frown upon using anti-anxiety medication, but from time to time I take 1 mg of Clonazepam to help me relax. I keep a small supply just for the days when the tinnitus is especially bad, to help me get through it. I also play white noise while taking a bath, use the Clonazepam, and soak in the hot water to relax my muscles.
With relaxation, I can lessen it a little, or perhaps it's just that my perception of it decreases. Still, it's always there, like a dark passenger that refuses to leave my head. I wish all my fellow tinnitus sufferers relief, and I pray that one day spontaneous recovery will occur.
