my initial thought was frogshit also, there really are options as mentioned.
you can get tinnitus from abusing codine meds also, my drummer has it so bad its starting to effect his ability to really hear what's going on during a song. His is from codine and other meds he thinks.
i have it a little bit also, ya just gotta be careful, you wont know youre or gettting it till one day youre like, fuck i think i have fuckin tinnitus! that not very fuckin cricket now is it?
its that simple.
