I don't like doing shorter fasts because you only experience the worst part of them. The first 3-4 days are the worst and then everything clears (pre-existing conditions in skin/joints/intestine, mind fogginess, etc). Going out of the fast is a good time to experiment with food/situations and see what could be causing some of the issues you've been experiencing (if any). I usually go for a 7-day water fast twice a year (and just completed one a few weeks ago). The results are obvious to me. YMMV. Mandatory warning: I'm not a doctor and this is not medical advice. Talk to your doctor.
