Prepare for potential side effects that you might experience during the Master Cleanse diet.
Some people experience potentially unpleasant side effects with the Master Cleanse, including headaches, diarrhea and nausea. Many also suffer from fatigue while on the diet, which can make it difficult to focus on tasks.
You may find it helpful to do the Master Cleanse over the weekend or during a time when you can be at home. As the body goes through the detoxification process, frequent trips to the bathroom are not unusual. You may also find that you need additional time to rest while using the Master Cleanse diet.
