It might be worthwhile to consider an over-the-counter sleeping remedy. After one night of torment with screaming T that kept me up until 3:00 a.m., I went to the local drugstore and asked for a recommendation. The pharmacist suggested generic doxylamine succinate, the same thing that's sold in Unisom.
Dosage is 25mg per pill, but based on what I read in the reviews on Amazon, many people get benefit from splitting the pill in half. I did that, and slept through the night for the first time in 2 years. I take half a pill almost every night about an hour before bedtime, then I drink a cup of Celestial Seasonings Sleepytime Extra tea at bedtime. I now sleep 7 to 8 hours every night.
I don't know how addictive doxylamine succinate is long-term, but constant sleep deprivation is detrimental to the mind and body. Getting 7 to 8 hours of sleep helps me to cope with the tinnitus.
