hub and I have 'fasted' many times over the years, and for many different reasons,
and thus we, for our own selves have found-out what our 'limits' were/are and the many
benefits...'caffeine' and medicine' should be weaned gradually, before trying to 'detox'...
being on any kind of 'serious meds', then you should consult your 'doc'...
hub, has an amazing endurance and stamina that I don't have with some of the different
'fasts' that we have tried...
we learned from our very first 'water-fast', that hub had a much longer endurance time than myself,
I actually did become very weak after a certain amount of days, and almost passed-out with hub
having to carry me back into the house, as my heart had enough of me denying what I needed to
stay afloat
...I actually envied him his endurance, as our goal was to 'fast' for about 10days...
yes, I have since discovered that I have 'mitral-valve-prolapse', so that was my body telling me,
'enough'...
the very BEST FAST that we ever did and had the greatest results from, what a 'grapefruit' FAST...
hope this helps in some way...
always listen to your body, if you are a serious 'detoxer', for any reason...
