You don't need to fast and it probably won't make anything easier. Once the drano begins to work, you will begin flushing out the pipes. The beginning is the most 'productive' it eventually tapers off into clear liquid. That's the goal. Your ride to the appointment won't be a problem. You get there, they stick you, you feel like you need a nap all of a sudden then somebody is asking if you'll like some juice because it's over.

My guess is you'll wonder how come you didn't know there were so many pansies here. We'll look for your gibberish video on youtube.
