Watch out taking Gabapentin and tetegrytol, the wife was on them for years because of trigeminal neuralgia, they are not known as stupid pills for nothing, not only stop misfiring nurves from working but seriously slow the rest down.
Had tinnitus for 30 odd years myself, due to working in heavy industry, no help offered by the NHS so just have to live with it.
Been on Amytriptaline for years for other issues so the nurse pain killer has no effect on the tinnitus although it does slow the brain down.
Never been a fan of self medication especially knowing the long term damage the likes of Tegrytol does to other major organs which is why you are supposed to have regular blood tests done, which you don't get when self medicating.
