Carrot juice, etc.
In order to boost my immune system (I have battled CFS for years), I am making fresh carrot/celery/parsley juice for breakfast. This, of course, is a lot of work - peeling the carrots, washing out the juicer, cleaning up, etc. My question is, how "fresh" must this juice be to be effective? I mean, can I make enough for two days perhaps and refrigerate half?? Thanks.
