What is the most challenging day?
There is absolutely no way of knowing this. Everyone is so radically unique in the way they experience this detox process. Even people who have been through my protocol 2 and 3 times, still have vastly different experiences each time. Some people even start to feel detox symptoms on Day 1. And of course, some feel excellent everyday right up until day 7. Just go with your own flow, let it be what it will be and trust the process.
