water fast?

i am thinking about starting a water fast to help me get closer to the lord and i hope in getting closer to the lord that i will be able to hear what i am to be doing. i am unsure at this time how long i will be doing it for but i hope to do it for at least a month to start out with or longer if i need to. if any one reads this please tell me what your thoughts are. ( by water fast i mean nothing goes in my body but water.)     I DID NOT DO THIS as i read more into it and it is really not that good for you
