What a good idea to plan your meals/snacks the night before! I guess it is obvious, but I hadn't thought of it (no organisation, me!). I had the same problem as Kate today, too few cals., but not hungry. Not my usual worry, obviously, or I wouldn't be talking to you on this forum
I'm leaving it until last thing before I go to bed to have a drink or snack to bring the calories up a little. I think I will try planning as you suggest.
