Breaking 8.5-day fast tomorrow - Refeeding thoughts.

Tomorrow, I break the fast. But when I was shopping for food to store up a few days ago, I noted with dismay that Watermelon was not available...

So instead, I bought carrots (for juicing), a large number of red apples, and even more oranges.

I know citruses are not the right food for the initial breaking of the fast. So it is down to carrot juice OR whole apples.

Which should I choose? How much at what frequency?
