Usually if it was temporary it would have gone by now..
Although some people say up to 6 months and even a year it could go away.
But the best advice i can give is to try and accept it now so that if it is permanent, you're already in your way to living with it.
And if it goes away, happy days!
You can try using masking sounds when sleeping. I found nature sounds like rain or storms good for me. Others like to use crickets/cicadas.
You can just YouTube sounds.. try not to have it too loud. But just enough to take your mind off tinnitus and on to the sound.
Hot showers sometimes calm my tinnitus. Try having one before bed.
