For what it's worth, my psychiatrist prescribed pregabalin. I took it for a few days, 3 x 25mg per day. Guess what happened? Last Monday morning I sudden came down with some weird tinnitus/sound distortion, but it later went away after a few days, but it scared the fucking bejesus out of me. Guess what happened then? I looked it up and sure enough, IT'S OTOTOXIC and quite toxic in that regard, so I fucked it off and won't ever touch it again.
The same goes for SSRIs, which is a right fucking shame because they offer so much relief for anxiety, but they cause tinnitus and sexual dysfunction, among a few of their many side effects.
You just can't win, can you?
