I use CBD oil and RSO oil, Rick Simpson Oil, that`s with THC( it is illegal), my tinnitus gets better but i don`t know for sure if it`s the oil or i am habituating. The RSO oil gives me a good deep sleep that makes me more rested so i can handle my t better, i think. RSO oil is used when people have cancer, google it, it works much better then CBD alone, it is a wonder medicine they say! Only negative, it`s illegal and you can get a little stoned, i don`t mind that because it let me sleep well.
You can buy it from cannbis growers or make it yourself with cannabis, in Holland where i live it is easy to get!
