Well, I'm back after a very long absence from the Tinnitus Talk boards. Since this is the thread where many people are describing their experiences with different antidepressants, here's my update on how things went with Duloxetine, i.e., the generic form of Cymbalta.
During the time I was on Duloxetine, I experienced almost complete relief from depression. Prior to starting Duloxetine, I was having suicidal thoughts daily, but with just one dose, the suicidal thoughts went away, and I was left with a much milder form of depression. It was so mild that some days, I didn't even feel depressed at all.
Shortly after starting Duloxetine, I started to experience musical tinnitus. It lasted about 2 or 3 weeks. However, right around the time I started Duloxetine, I had to run the air conditioner almost every day due to hot summer weather. The musical tinnitus often kicked in whenever the A/C was running, and sometimes (but not always) it would stop when the A/C stopped. So, although I initially attributed the musical tinnitus to Duloxetine, it's possible that it was caused by certain types of ambient white noises, and it would have happened to me that summer even if I hadn't agreed to take Duloxetine.
Duloxetine never helped with the ear pain caused by noxacusis, nor did it help with the one-sided headache or the high-pitched tinnitus, but I stayed on my 60 mg dose for about eight months because the relief from depression was such a godsend. I would probably still be on Duloxetine today except for the fact that I was constantly hungry, and I gained between 6 and 10 pounds. At first, I thought that was a small price to pay for the improved psychological health, but then I decided to quit Duloxetine anyway, not so much because I was upset about the weight gain but because I wanted to see if my brain chemistry could do without it. By that time, the severity of my noxacusis and tinnitus was somewhat diminished, due to the mere passage of time, plus judicious hearing protection on my part, so according to my reasoning, "I have less reason to be depressed now, and therefore less need to be on an antidepressant."
Under my doctor's advice, I tapered off over the course of 28 days, going from 60 to 40 to 20 mg. I was fine until three days after my final daily dose of 20 mg, when I was hit by physical withdrawal symptoms such as all-over body aches, insomnia, and brain zaps. When those physical symptoms faded away over a week later, I was left with the horrifying realization that my depression was 100% back, including the suicidal ideation. It didn't help at all that toward the very end of the 28-day tapering period, I had an accidental noise exposure without hearing protection, resulting in a major noxacusis flare-up. I'm sure you can imagine how much self-hatred and self-pity I felt because I was careless enough to have a momentary exposure to a loud sound, right when my brain chemistry was becoming vulnerable again.
I'm currently debating whether to speak to my doctor about getting back onto Duloxetine, switching to a different antidepressant, or re-exploring ways to improve my brain chemistry naturally, such as exercise.
One other curveball to contend with: while I was away from the Tinnitus Talk boards, I developed pulsatile tinnitus in both ears, on top of the existing high-pitched tinnitus and the noxacusis that I'd already been dealing with, so now I have to see an ENT to find out why.
In short, Cymbalta or Duloxetine is awesome for depression, and I'm so grateful that it exists. But oh man, quitting this medication is really hard, even when following doctor's orders for tapering the dose slowly. That final leap from the lowest dose to zero is like jumping off a cliff without a parachute.
