Hello All.... I have for the past 30 years fasted 2-3x per year. I started doing the 3 day fast the I tryed 7 days, What I learned was the fun starts after 3 days. I experenced a high level of energy, my mind became very clear and focused a real natural high, there was no urge to eat that was gone. I fasted in 2001 for 15 days (Dangerous) Again the experience was incredible however on the 10th day the food dreams started and the headaches started but still had the will to keep going (big mistake).
