I've been off them for a while, but in addition to permanently worsened tinnitus, I've also been left with reduced "tingly" sensations like those experienced during ASMR and orgasms. I experienced no benefit from the half dozen that I tried. It really, really, really sucks, and if I could go back, I would have never taken them. Ironically, they were prescribed to me because my doctor was too afraid to prescribe anything else for fear of side effects.
