You may experience withdrawals on the first few days of the cleanse if you have a lot of inflammatory foods in your normal diet, such as sugar, dairy, gluten, caffeine, meat and alcohol. The symptoms you may experience are headaches, nausea and/or mood swings. This might sound drastic, but for most people, if they experience them, they are mild and normally only occur on day 1. The feeling at the end of a cleanse makes it well worthwhile pushing through this initial discomfort. In fact, to date, everyone who has done a Happiness Transformation cleanse said they would do another!
