OSMO PREP QUESTION--Think I messed up

I know it says to drink clear liquids, but in my lightheaded daze, I picked up unfiltered apple juice. I drank about a cup of it before I realized. I called my doctor and he said to "Do the best you can, and we'll see if we can see anything tomorrow." I'm confused. I don't want to continue with this awful prep if they aren't going to be able to see anything. HELP!! 

i couldn't finish the prep! i was too close to throwing up so my doctor told me to drink 2 bottles of magnesium citrate instead. i'm afraid with these 2 things, i may not get accurate results. it might've been more like 2 cups of apple juice.

It is except that tryin drank unfiltered apple juice which is milky with possible pieces of apple.
