I've been diagnosed with fatty liver disease and i was wondering what drinks i can have, i know water is the best but what else can i have?

Non-alcoholic: It's your choice. I'm going to assume this is common non-alcoholic fatty liver and not a mimic such as hepatitis c or a medication allergy. Fruit juices aren't always as wholesome as one would think, especially the sugared ones. Your physician would probably like to see you stay physically fit and trim -- this is the key to management -- so grab your water bottle and hit the track. Save your life.
