Breaking caffeine addiction without ruining my life

is pretty hard.  I've never had caffeine headaches before.  I guess I didn't have coffee as frequently as I thought in high school.  I had coffee... three times a week at most in high school, and here, every day.  And then a cup in the morning felt like I drank nothing so I would drink another in the afternoon, and then I would feel the effects.  And then I didn't drink any one morning and couldn't function with eight hours of sleep.  That's when I was like..... "Dang.  I learned about this stuff in health class.  I need to stop before it gets any worse."  So... I haven't had any coffee for two days now and oy.  I just crashed for no reason for two and a half hours... on top of eight hours of night's sleep.  Wtf.  -sigh-  I think I'll take it gradually and drink tea instead.
