I had a bout with vertigo once, and it was scary and difficult (and dangerous) to do anything requiring focus and balance. I can't imagine what it is like to deal with it long term. Luckily my vertigo was BPPV ( benign paroxysmal positional vertigo) and was cured with the Epley procedure. As others have said, keeping well hydrated and getting appropriate nutrition through good food choices can do a lot towards improving some symptoms. Dealing with long-term chronic health issues can make it difficult to do the things that might help, so it can be a catch-22. It can also be difficult to get a proper diagnosis for an uncommon condition, so you often have to be your own advocate and do your own research into your symptoms, and then find a specialist.
