Try different strategies when trying to go to sleep with tinnitus. Make sure the room you are sleeping in is completely dark. When you lie down, try to think of relaxing things, such as ocean waves or relaxing on a beach after sundown. Keeping your mind occupied with relaxing thoughts will help you fall asleep fast.
If your tinnitus is excruciating and your doctors are unable to help you, try Eastern and alternative techniques. The human body is not fully understood by Western medicine, despite its many wonderful advances. Hypnosis, Yoga, Tai Chi, acupuncture and even Reiki all have relieved tinnitus for some sufferers over the years.
To keep tinnitus from driving you crazy, project it out into the room. Visually pick some corner or object in the room you are in and mentally associate that as the source of the sound. If you pretend that it is not within you, then you can mentally relax that there is nothing wrong with you. This improves your mood and blood pressure.
