How you fast is between you and God. We are calling UBC to a 24 hour fast before Spirit Alive. If we confess our sins He is faithful and just and will forgive us our sins and purify us from all unrighteousness . Set aside time to be with the Lord. Persons fasting for 24 hours may experience headaches especially those who are caffeine drinkers.
Dry mouth is also common.
Those who are fasting for extended periods may also experience fatigue and mild dizziness when changing position quickly. Those who are planning a prolonged fast should begin the fast and end the fast gradually. This may mean starting with smaller meals the day or two beforehand. You could eat only raw vegetables and fruits the day or two before or drink only juices before you begin. End a prolonged fast the same way.
