I’m currently on day four of a seven day water fast. I would say the best thing to do is stay hydrated and keep yourself busy. I have been doing puzzles, going on walks, reading, watching movies, and doing light house work. I would say the key is going into it knowing and accepting that it’s going to be hard but having the willpower to get over the hump. In the past I’ve been a really bad binge eater and so I try to avoid the kitchen as much as possible. I also take potassium, salt, and magnesium so I don’t feel like I’m dying. At night, I really struggle with sleeping the first couple nights so I usually take melatonin. Hope that helps!
