I tried to do without the coffee, I spent a whole week with migraines. I missed class or left class early cause I couldn't take it. The whole idea of avoiding coffee if I remember correctly is that studies have shown it slows down weight loss and induces cravings. While I do have cravings I find myself less hungy throughout the day when I have my caffeine (coffee!) in the morning. I really don't think I'm ready to give it up, plus how am I to stay awake at night to do homework If I am wrong about the studies and reasons behind avoiding caffeine can someone please please let me know. I hate to walk around with false information thank you
