It is what it is, give it some time and you'll more or less forget it's there.

One cool little trick for temporary removal is to cover both ears with the base of your palms, then drum with your fingertips on the base of your skull for about 30 seconds. You'll get maybe 10-20 seconds worth of pure silence after you take your hands away, sometimes it won't be quite as loud when it comes back too (can be useful if its keeping you awake). Doesn't sound like a lot, but if you've lived with non stop eeeeeeeeeeeeeee for years on end, it's honestly pretty surreal to not hear it at all, even for a few seconds.
