I just started the Master Cleanse today. I've done it once before and I would do the salt water flush in the evening. I stop drinking my lemonade around 3 or 4 and then drink the salt water around 6 or 7. That gives me three hours of no lemonade so it's almost like waking up with an empty stomach. I also like doing it this way because the salt water really fills you up and helps you get through dinner time. Since I was doing the salt water in the evening I would drink the laxative tea around lunch time. I plan on doing it this way for the cleanse I'm doing now also.
