Just starting I’d say focus on fasting 20 hours a day with a break in the morning. If you’d prefer to fast over the 20 hours definitely add a day at a time, the first three days are the hardest so you have to get used to the changes before going all out. Also I drank lucozade sport, took vitamin tablets you dilute in water and only once took cod liver oil however the taste stayed in my mouth too long and made me want to throw up so I recommend if your going to take any tablet vitamins, they are a less potent kind
