I just wanted to thank you for posting this. I´m a severe caffine junky, drinking several cups of coffee in the morning and iced tea throughout the day. I´ve been going to the doctor for a couple years trying to figure out why I´m so tired, suffer from alot of all over aches and pains, severe anxiety/panic attacks in the evenings and mood swings. Doctors ask alot of questions and want to know if you smoke, take drugs or drink alcohol, but not one has asked me how much caffine I consume. I´m also overweight and haven´t been able to tackle it because of the fatigue and pain. My life is pretty crappy right now from all this. I´m going to wean myself off the coffee and tea and see what happens. Again, thank you because this could be the key to me getting my life back :-)
