hi there lolo, id say go easy on yrself. you will experience strong detox symptoms if your diet has been salty, fatty, sugary etc. Take it 1 day at a time, youll need a lot of rest and life doesnt always allow for this. Im an avid juice faster and i think water is deff harder still. Have you researched The Master Cleanse
and juice fasting as well? These may help you to continue an extended fast and still feel energised. I would urge any 1st time faster to get buddies and advice from a natural health practitioner who is knowledgable and positive about the benefits of fasting. Hope this is helpful to you, love Emma.
