Not much you can do, just drink 80ozs of water a day or more. It will really help. Be careful when getting up from a seated or lying down position.
As far as I know, it should be low. It's much better than high, so you are perfectly fine.
Drink a lot of water, be careful.
I had that too, it was not nice! I had to move really slow. The only thing that helped me was drinking plenty. I already thought I was, but my doctor had me keep track and I was able to see I really wasn't drinking enough. More water, Gatorade etc made that dizziness go away.
