Fasting

Anyone have any tips to help water fast and or have any results of themselves? I’m going to start water fasting tomorrow for the first time. I’m trying to cleanse myself and begins my journey to losing weight. I’ve watch multiple videos of people’s journeys and their results so I’m going to give it a shot.. also has anyone ever done coffee enema? I’m looking for advice on that as well. I’m not really sure what that is and or what it does?
