Dear user.. a water fast is for someone who is very experienced with fasting.it is not for begginners, furthermore a water fast flushes the body of toxins at an extremely fast rate..which can be overwhelming..my recommendation is that you start with a juice fast..this way your body is still getting the nutrients it needs, so you will not feel totally deprived..you may also want to come down to eating raw foods or just fruits and vegetables a few days before you start the fast should you decide to give it a go again..I will say you did a heck of a job with going 8 days on a water-fast.. but you would have definetly gone father on the the juice-fast..don't give up.. just start again when your ready on the juice fast and you will still experience all the benefits..of the water fast..and you won't be going crazy..
