Ann - I am not too sure what causes a day four. I was asking myself that just the other day. I want to learn more. I have been told it has something to do with the way your brain rewires itself. Maybe someone else will post and explain to both of us exactly what happens. Also not everyone has it happen on day four I have heard people say it happens for them on day 3, but that is where your journal comes in. It will tell your.
