I have tinnitus and after a while the brain ceases to 'hear' it. It doesn't bother me now at all.
The nights will be the worst because of the silence, you need to fill that silence with another noise rather than the tinnitus.
Two options, are a white noise machine, you know the sort of thing, they also play gentle winds, waves breaking on the shore etc. Or a good old simple fan. You don't have to point it at you if you don't want the chill but it is a good source of white noise.
