Deciding how long to fast can be a bit tricky as there are many factors to consider. I find that it can be beneficial to have a target for your fast AND at the same time, listen to your inner guidance (if you can rely on it) or to someone who is experienced with the cleansing process to guide you. Ego has no place in fasting and can cause one to go beyond the point of it being life affirming. Start out slow if it is your first time. 3 days of juice fasting is a great place to start or you can certainly come join us at a future retreat!
