Are you a Christian? Because I can refer you to some great Christian fasting books.
Generally, only drinking water is fine, as long as it is for a short time. (Especially if you don't have a lot of experience with it, you probably don't want to do a water fast for more than a day or two, tops.) You can even do a *breath fast* (no water) for a day, but I wouldn't do it for any longer than that.
I skimmed a good book about fasting at, of all places, Jamba Juice, the other day. I'll see if I can find it and link you to it, but if I remember correctly, it recommended a gradual transition back to eating (so, don't sit down to a steak or anything right after a fast), and a slow transition to fasting is a good idea, too (to prepare your body for the fast). Also, realize that you'll be grumpy, tired, etc., especially at first, so if you are the only one around to care for your children (if you have any) it might be a good idea to wait until someone can help you.
I hope some of that helps. If you are a Christian, you can do a search for books by Bill Bright on fasting.
