Personally I don't have anything after nine at night unless I've been out.
During the working week I have breakfast at nine in the morning so apart from a cup of coffee with cream when I get up, so I guess I'm basically fasting for twelve hours a day. I have a little bit of the dawn phenomenon but by breakfast I'm usually back in the 4.6 to 5 range.
Before diagnosis I was never a breakfast person I could take it or leave it. It's only for the Metformin that I make sure I have one now.
