Does it have bad effect on health if I drink a lot of coffee everyday

Like many things I think it is a case of not overdoing things! From what I have read and understood in the past, having two or three cups of coffee a day can be of benefit; yet having more than this regularly can become bad for you. Yes I do use coffee when I wake up to kick start my day! And I also try not to drink coffee after 5 in the afternoon so I don't end up having trouble sleeping. I am not a good sleeper as it is so don't wish to make it harder! One thing many people may not take into consideration is that many soft drinks too also contain caffeine so we actually end up consuming more of it daily than we may realize.
