I didn't have to start anything until the day before, although I ate smart the day before that. Liquid diet during the day and the solution that evening and the next morning. The next morning was completely unnecessary and all it did was make me puke. I'm not drinking the morning dose next time. I think a lot of people must think they will starve and eat everything they can for days up until they have to go liquid, and that's why they give you that extra dose.
