I have taken caffeine out of my diet nearly a month ago. I have went to starbucks twice a day For the past couple of years and also taken a excercise stimulant called ripped fuel for the past 3 years a few times a week. I am seriously so ill. Heart palpitations, nervousness, indigestion, diarrhea, headaches, really I feel like death. Is this normal? Someone please help!!!! Chame16922@aol.com if you have advice. Thanks
