Your first time grocery shopping for yourself is going to be a little overwhelming, but it just gets better after that! Your food journal doesn't have to be anything too detailed, but jotting down things like "finished blueberries in two days" or "ate two cookies after dinner" can be a helpful resource to look at before your next visit. Your eating habits change when you're on your own for the first time, so keeping track of your new patterns will definitely help you figure out what you need.
