Try the notebook trick then. Take a pad of paper or notebook everywhere with you and when you think of something you need to do wrt house move and car sales/purchse write it down. Then give yourself an hour a day in which to deal with what is written down. It really helped my dizzy spells doing this. Also keep a packet of lollies with you to give yourself a sugar shot if you feel faint. But mention to your midwife that you are feeling like this because she will be able to rule out anything medical being the cause of these dizzy spells.
