Changing Sounds When I Sleep and a Question About Sleep Meds

I have question. My ringing has been getting quieter these past few days and now sounds almost like a hissing. It is primarily in my left hear; however, I sleep on my right side and notice that the ringing gets substantially louder as I sleep on my right. I will try to flip over and notice that the ringing goes down. It does not disappear but changes pitch and volume.

I was wondering if anyone has experienced this?

Also, I went to the ENT yesterday and of course, to no prevail, I was told "it will either go away or it won't". My sleep schedule has been horrible. The doc suggested some low dosage anti-depressant to help me sleep. I cannot remember the name and was wondering if anyone has had experience with this drug? It is an anti-depressant but in low dosage. If so, did it help with sleep and what were the side effects?
