I have done it many times.
In connection with liver flushes, and without.
My experience is only positive.
Whatever you do, you should always listen to your body.
How much water do you drink on a regular basis?
Everybody on curezone have learned that half your bodyweight in onces, should be consumed as a minimum intake!(150lbs or 75kg needs 10 cups or 2,5 liters)(have me excused, I am not familiar with american formulas!)
If one does cleansing that pushes extra stuff out, one needs to add extra.
- just remember to also add extra vitamins and minerals as they are flushing out too.
Ooops and! some people does not need this much water everyday, as it will make them swell.
If I drank 3liters of water in my clima, I would have to switch my office chair with a toilet.
When it comes to waterintake I feel it is better to take to much and adjust, than the oposite.
