Hi Scone - If you have 22 points try to use them on healthy things and keep to them otherwise it may help for a few weeks but longer term can make it hard when your body adjusts to that number of points. I actually think WW gives you too few points and that you should gradually go down to their recommended points, otherwise you can yoyo with them. But you are right with the half the points thing. If you only eat half it is half the points. HTH
