Please, don't hate on me too much, for this post, I'm just very curious about the topic, and even if I have very little knowledge, I can sometimes contribute to the topics on this forum.
Maybe different people react to the treatment in such varied ways, because we all have different bodies?

I have read the above article, and it basically says that if your body is lacking Magnesium, that any of your temporary hearing loss could become permanent hearing loss. Is this, what could have happened with Alan's treatment experience, where he had his tinnitus increased for longer time? Maybe there are other nutritional deficits inside one's body, when the Lenire treatment is not working correctly.
Neuroplasticity, immune system and general health, seem to be playing a big role in recovering from tinnitus, is it not right? It looks like there are a few things that can silence tinnitus, for example Lidocaine or being in a vegetative state. So there must be a way out of this maze, no matter how bad your tinnitus is, or for how long you had it. As tinnitus, sufferers we seem to have quite fragile auditory systems, in general, which often alleviates more problems, like anxiety and concentration problems.
I think that bimodal stimulation has a great potential, assuming that the electrical stimulation is actually applied the right way. For example, stimulation the Vagus Nerve with electrical pulses, does not seem to work, when you connect the wires to just human ears.
May be it, that dead hair cells only cause permanent hearing loss, and the ability to hear certain sounds, but this does not necessarily have to result in tinnitus, as long as other parts of your auditory system, will regenerate well after the hearing loss which when the hair cells died. Also, maybe when scientists re-grow ear hair cells in clinical study patients, this process later stimulates the whole auditory system of the patients, and tinnitus disappears, as the whole 'phantom pain' or 'phantom sound' effect is just not needed anymore (?)
It seems that bimodal stimulation causes some hearing damage, which later should heal, and promote further healing, therefore your hearing and tinnitus should improve over the course of the treatment.
DCN is mentioned in my above post. Phantom sounds are being created by fusiform cells, which seem to come out from DCN.
Dr. Tzounopoulos is looking for a tinnitus treatment, that could be a modified version of Trobalt (Epilepsy drug.) This new drug would try to alter physiological reactions inside DCN.
On the below link you can find more information about the process.

I think that we are very near to discovering a cure drug for tinnitus and epilepsy, at the same time.
