You are getting sleepy... and some relief from tinnitus! Hypnosis is said to bring a reduction in tinnitus symptoms for many sufferers, so why not try it yourself? Find someone locally who has great references and has dealt with people in your situation before and see if they can help you with your disease.
It is vitally important to let your family doctor know if you're taking any supplements, especially if you're on any prescription drugs. The interaction between supplement and prescription can actually bring on the symptoms of tinnitus, so give your doctor a list of any vitamins, herbs, or homeopathics you're taking.
Finding a support group for sufferers of tinnitus is a great way to be surrounded by people who understand what you're going through. If you can't find one locally you can always join a group online or start posting on a tinnitus forum. You'll find both medical professionals and your peers, and they'll all have valuable information you can use.
