I am not a coffee person firstly, however tea that is a different story, for me I have to have a cup of tea. It is the first thing I do in the morning and believe me I can't function if I don't have at least one cup of tea in the morning.... It seems the only thing that can get me gear up for the day and if I don't have much of a cup of tea like if I have to start my day in a rush and just have a few sips then I get the worse headaches ever until I have had another strong cup of tea. However this may be more of a culture thing not that it really anything to do with the culture but I am from the UK and been drinking tea since I was young.
