We removed ours a few years ago, and found the easiest way was to spray water on about 2 feet sections at a time the it can easily be scraped off with out that awful dust flying all over the room..
Remember that popcorn ceilings usually have asbestos in them for one. Cover your floor. Wear a protection mask and spray with water and and scrape with a big putty knife. Very easy
