No Caffeine

I have decided today to give up the caffeine. It keeps me up at night an doesn't let me get a good nights sleep. It also makes me tired during the day when I have no reason to be so tired. But man I gotta tell ya, it's only been a few hours and my head is already starting to hurt. I know it is a good thing because that means that my body is detoxing all the CRAZY amounts of caffeine that I had put in it over the past few years in college. I am just afraid of how I am going to feel tomorrow. How bad will my head be? Will I be able to stick it out or will I give into the pain? I hope I won't. I know I have tried this before and it has been bad. I've been cranky and my head has felt like it was going to explode and I literally felt like I was sick (fever nauseous etc.). Here's to stickin it out!
