Yeah 

 If you can do 3 days, why not a 5-day juice fast? The first couple days are usually the hardest (hunger), so imo just dig deep and go for the 5 😉 I'm in the middle of a cleanse myself.. epsom salt, psyllium husk, de-parasite and de-heavy metals. There's more, but I don't wanna gross u out hehe - u can do it! 💪   

 I've done a 7 day water fast before! It was pretty challenging but I did it to heal a health issue I had. I've also done juice fasts. They are easier to me than water fasts
