Hi sewerrats, echoes,

No I haven't taken AD's very often and not in several years. It possible that other meds contribute to it.

Echoes, The machine is called a Sound Therapy System from Sound Oasis (in UK). It generates a variety of sounds. I use a summer nights sound. It can be used like an alarm clock but I use at bed time on a one hour snooze setting. It masks the tinnitus while you fall asleep and it has certainly helped me. The snooze time is variable.
