I used to have similar problem, due to my eustation tubes in my ears being different diameters. What I do now is on my way to the dive is start to clear my ears. Kind of like warming them up. I found this to help with vertigo/dizzy spells a lot. Also try to stay away from your dive buddies bubbles this I also found to cause some vertigo problems. As for the decent you should let enough air out to just start to sink and be able to control it. But keep in mind you should not have to have your bc fully inflated to stay on the surface. If that is the case you could be overweighted which is not helping under water as well.
Good luck
