Day 1 Headaches, nausea, had to take 200mg advil Slept amazingly well (felt better on 7 hours sleep than I usually do on 8.5) 4 cups of green tea (est 120-160mg total caffeine)
Day 2 Barely noticeable headache 3 cups green tea (est 90-120mg caffeine) Felt much calmer and relaxed Face was flushed, not sure if a withdrawal symptom
Day 3 (today) No headache Feeling relaxed and focused Planning to cut down to 2 cups of green tea (estimated 60-80mg caffeine)
From what I've heard, it can take more than a year to be completely free from the symptoms, so I'm in it for the long haul. My goal is to be completely off caffeine by the end of the week. Check out the book Caffeine Blues to get a better understanding of how dangerous caffeine actually is.
