If you are interested in fasting and have never fasted before, I would suggest starting the same way I did the first time that I ever fasted. Just try to fast for one day and remember to pray also. I consider fasting as a way of humbling youself before God.
I drink water only when I fast. I would be glad to meet you in the chat room sometime and answer any other questions that you may have.
God bless you Zule and may He see your hunger for getting closer to Him. The scripture says "Seek and you shall find. Knock and the door will be open to you.
