Trigeminal Neuralgia
"I am taking time-released carbamazepine for vestibular paroxysmia. I was experiencing machine-gun type tinnitus accompanied by vertigo for about 15 seconds at 45 second intervals. I started on 100 mg twice as day; I felt improvement within 12 hours. After one week my symptoms returned and my doctor increased the dose to three, then four times a day. It has greatly reduced the tinnitus and vertigo, though I still get it if I lean over or lie down on that side. I experienced severe drowsiness and occasional dizziness the first few days, and after 6 weeks am still sleeping about 2 hours more than usual. I have become extremely sensitive to the sun (must wear strong sunblock, hat, and polarized glasses whenever outdoors.)"
