Can anyone shed any light?
Having too many fridge magnets can make you dizzy, if you walk past the fridge a lot.
Check you haven't got too many.
LOL
I used to go dizzy and my vision go sort of cloudy when I stood up too quick, even fainted once. Doc told me it was low blood pressure and harmless (unless I started fainting all over the place of course). Happened more when I was tired and ill too. Unfortunately I seem to have grown out of the problem.
It's called fridgemagnetitis.
