pulp or no pulp?

ok.
i'm on day 3, and doing ok, except i don't have a juicer yet (it's coming). so, i've been using a blender. i peel the lemons and limes completely (but leave on the white stuff since that one post outlined the difference btwn citrus water and total juice), then i liquify all of it. my question is, does the pulp i'm drinking constitute as food that i shouldn't be ingestnig, or is it ok since it's fiber and citrus nutrients? should i strain it to pure thin liquid before drinking it?
it didn't address this in the book, and i'm really curious. i want to do this right.
thanks, good luck to all!
