I take Lorazepam on a regular basis, for the simple reason that it is the only reliable drug that can get me to sleep and I am guaranteed to have a low tinnitus day, the next day.
I'm very careful not to abuse it, however. Lorazepam has a very short half-life, so it is totally out of your body in about 3 and 1/2 days. Klonopin, if I recall correctly, has a much longer half-life, so it remains in your body longer. On average, I only take the Lorazepam about once a week, and I only take 0.5 mg. At that dose, there really isn't much chance of becoming addicted or developing dependency, and it always does the job.
