I am on day 2.. and have quite a headache. I cut out caffeine several days before, and did not have headaches on those days, but I am assuming that is what is causing them. Anyone have any advice on how to alleviate them? I've been drinking lots of water, lemonade, and herbal teas. Other than that, things are going well. I have not been too hungry, and am hoping to make it a full ten days. I tried once about a year ago and caved in after 5.5 days. This time, I'm hoping to do better since my job does not involve as much public interaction as last time. Happy fasting to all... I really appreciate this site.
