Scared to do the 3:6:9 cleanse

I really want to do the 3:6:9 cleanse but I’m scared about the mental and psychological battle. I work full time and go to school part time (after I get off work) so I do have a busy life. I also have binge-eating disorder. I’m scared about facing the cravings, constant hunger, and tiredness. I know I really need this cleanse, but I don’t know if I’m strong enough. I’m also scared if it will not give me enough energy for getting schoolwork done.
