Definitely. Green tea (both decaf and regular, and even a lot of herbal relaxing teas without real green, black, or white tea); coffee; and energy drinks, all increase my tinnitus by at least 3-4 levels every single time I drink them (it's usually about a 4 or 5 these days).
My tinnitus in 2020 was a level 8 and I wanted to die. I switched to an all natural diet of only fruit, veggies, nuts, and seeds and eliminated Gabapentin and Xanax, and all processed foods, dairy, and sugar, and it went down to a level 3 or 4 in a year, thank God! It saved my life. I lost 60 lbs too!
When I start eating like a typical person again and eat at restaurants, eat canned and boxed food like soup, cereal, and sugar, it gets worse, but not half as much as when I drink coffee, tea, and energy drinks. I still drink them, but I know my tinnitus will be up a few levels for that day and often the following day or two as well.
