If you do not want to put out the money for a white-noise generator, you can always turn to a regular fan. The repetitive motion that you will experience with this fan will allow your mind to gently fade away into a dark and peaceful sleep. It will also blow a breeze on you, allowing you to sink under your covers for a more comfortable night of sleep.
Be aware of your unfinished business throughout the early part of the day and try not to leave anything too important on your plate. That way, when you lay down at night, your tinnitus won't be aggravated while you are consumed in thoughts about what you failed to complete throughout the previous day.
Seek out alternative therapies. Have you seen a doctor and not much has been done? Try a naturopath or an alternative healer. You can also seek out acupuncture, massage and other alternative methods. Many people have success with these methods and seeking them out will help you to feel proactive about dealing with your tinnitus.
