I need to fast. I have health problems and I think fasting would help me to help my body begin repairing itself, but every time I try, after 2-3 days I get shaky, sick and very exhausted. I need to push past that and keep going for at least a few weeks with water and herbal teas. (I am not too thin or anything). So please pray I will have the willpower to do it and not eat something when I feel low energy or get headaches, nausea, whatever as my body cleans itself. Thanks.
