Hi Tristy

I to think that you are suffering from carb withdrawl as your body changes over to being a fat burner. Hang on in there. The next couple of days may feel a little strange. Make sure you drink plenty of water and do eat your veg. Make sure you get around 20 g of carbs. This is not a no carb way of life.

With regard to ketosis and the strips. How soon is shows can vary a lot and for some people it never seems to register at all. As already said they are only a guide and hence don't worry to much about them. You are in ketosis. Don't try to get the strips to go darker, there is no need.
