Each person will experience something different on a cleanse. For some it may be more energised and focused, others more fatigued and sluggish. This is all perfectly normal and is a sign of the body processing all the toxins from your body. Like anything in life it can be a bit of a mixed bag. Cleansing can bring up a lot of things that need to be dealt with, negative and positive. We say rest up and go with the flow, it's all a process and you will come out the other side changed for the better.
