Dizziness continues

So I am still having dizziness. Some days are remarkably better than others and I only have 2-3 spells. But other days are still pretty bad and it's every 1-2 hours. I can't find a pattern to distinguish the good days from the bad. On the good days, I've learned to live with the 2-3 spells. But on the bad days (today) the dizziness can be overpowering. I wish we knew what was wrong and could fix it.
