The liquid diet is to ensure you don't cause your gallbaldder and other organs to work much. The liquid pretty much gets digested just by regular movement thru the GI tract whereas solids have MANY steps to take that include the gallbladder, liver and pancreas before the GI tract can take over.
You are almost there... keep up the hard work and you'll pass the finish line intact and happier for it!
