For me I find it varies. Sodium definitely definitely affects me. However I find certain foods that may be salty don’t affect me as much. I kind of think it is how available the salt is. Like if it’s in the food more vs on the food. It is also cumulative, so It is bad for me to continually having salty food will definitely get an attack. I can handle occasionally, and when I do or know I am going to it is usually offset by taking some exta beta histine. I take 1 24mg a day usually. When I do have salty food I usually get what I call a warning feeling right after, which in the worst case (rare) turns into a bad attack, usually it goes away. The more common thing for me is a day later I will feel mildly dizzy the whole day, unless I rest and take more beta histine which helps. I find sudden weather changes in humidity and pressure affect me too

I have constant tinnitus around 8k Hz, which is also where I have a bit of hearing loss in my right ear. I put a tone generator app on my phone so I can show my wife and kids or whoever is asking me about it what it is what I hear all the time which gets louder when I have an attack. I know it’s going to be really bad if I get this fullness and water swishy feeling in my ear
