I have finally decided to start my fast tomorrow. I've fail numerous times before but this time i am committed and determined to succeed. There' re a few reasons why i want to complete it. Most important is for my health. Im hoping to heal my digestive track and colon. I know that breaking the fast is most important and crucial for the healing process. The other reason is im hoping to loose the extra weight that i've put on in the last 3 months due to my extremely poor eating habbits and bingeing. I've fasted for couple days before only but what i do remember is having these extreme headaches which made me sleepless. Can you take painkillers on a fast? Like Advile or Ibuprofen? also, can i drink tea on a fast? like very simple green herbal tea??
