@julieo4 Julie, thank you for your reply and
I had quite a bit of communications with the medical team, the implant manufacturer's engagement manager, as well as doing my own research. I got several suggestions, most of them similar to what one can find searching on the web. Relaxation exercises and stress management techniques were recommended as being effective.
Like you wrote, everyone is different. Tinnitus being a neurological issue, there are no "one-size-fits-all" solutions.
Following are a few of my personal trial-and-error experiences.
During the post surgery days I had received the recommendation to take Ibuprofen 3x200mg every 6-8 hours as needed against pain, as well as prescription pain and anti-nausea medication.
To help getting better sleep at night, I took Melatonin 20mg and Valerian capsules.
Searching on Google I found an almost endless list of medications and supplements that may/can/will worsen tinnitus, and the usual statement "...consult with your physician ". The prescription pain and anti-nausea medications I got were mentioned, too.
Melatonin and Valerian were also listed among those that taken over longer time, in particular at higher dosage might cause addiction, and stopping to take them could cause withdrawal symptoms. I had taken them before but not always, nor ar higher dosages.
I stopped taking Melatonin, Valerian, Ibuprofen and Pepto-Bismol, and within 24 hours the tinnitus improved significantly. Except for the first 3 days after surgery, I did not take any of the prescription drugs.
If waking me up at night, I do relaxation exercises until it quiets down and I go back to sleep.
Again, those were my experiences to date.
Implant activation will be this coming week and what happens afterwards remains to be seen.
