This is good information. I have a question though. Could you fast 3-4 days a week for say 6-8 weeks and get to the 4th stage of cleaning, or would you always stay in the first and second stage? I have to sing on the weekends, and it seems to affect my voice when I fast. Also, my friends always want to eat on the weekends. I know I should be strong, but I can't do anything about the voice thing, it's for church. Thanks for your help.
