I was falling twice a week or more, some weeks a lot. I was covered with bruises. After I found out how CCSVI works, I realized I have to keep my head upright. Now, especially after I have had to bend down, or when I feel dizziness, I immediately put my head upright. This works! I think it's gravity. I don't fall so much now. It's great.
I think I get more dizzy on account of gravity. I first thought about it when I was in a pool, and lost all sense of where up was. Proprioception had something to do with it too (I had less than usual in the pool, and the MS had affected it).
I don't know if any of this helps you, but I hope so.
