A pill which modulates the potassium channels temporarily to avoid tinnitus would have side effects, some of them can be classified as serious side effects. I personally don't want to risk these side effects even in case of bad T. My brain is the keeper of my personality and intelligence. I want to keep this in its origin. We all know that epilespy drugs or strong antidepressants can change things like personality in the long run.
Therefore I would prefer something like a one-time brain stimulation to reset my auditory cortex or one-time intratympanic injections with stem cells which are able to reorganize my inner ear in a way that my brain recognizes this ear is healty (all hair cells are working again) and there's no need to create these phantom noises any longer.
