I also can relate. Vertigo/disequilibrium is the one symptom I have which almost never seems to go away completely. For me it is better when I lay down and worse when I stand up, but that's the only real difference. I also have pressure issues in my ears. The ENT that I saw did a battery of tests and found that I have a minor nystigmata probably caused by my inner ear. He gave me a sheet of exercises to do, which I have done for several months and found to be completely useless. They are things like standing up and sitting down 20 times, then passing a ball from one hand to the other 20 times, then walking back and forth across the room twenty times, and so forth. It is hard for me to keep doing these every day when I find that it has not helped me in the least bit. The most helpful thing for me is getting a good night's sleep, trying to keep my neck and jaw muscles relaxed, staying hydrated, and getting out and walking frequently. I also suspect that I may have seasonal allergies which might be contributing to the issue by causing more fluid and pressure in my inner ears. My sinuses have been pretty bad for quite a while, and I don't think that is a mere coincidence. The hardest thing for me to do is to try not to get too anxious about the vertigo; it's really difficult to stay calm when you feel like the world is moving around and you're about to fall over. If I was in a minor earthquake I wouldn't be able to tell the difference!
