It'll pass and you'll start feeling great in no time. :) Detox is no fun!
As mentioned before the first few days are the worst. After the first days, hunger goes away and so do the major detox symptoms. Hunger doesn't usually come back, unless you've done a prolonged fast (like over 30 days). My hunger during my longest fast didn't come back until day 145, in which case, I stopped fasting. The hunger is a sign that your body is done fasting.
Keep in mind that chewing will trigger hunger (and start digestion). Best not to chew while fasting, or you'll never really be fasting.
