This article doesn't address the long term effects of Caffeine. Personally, I find that Caffeine makes it harder to slow down and relax. Caffeine makes it harder to sleep.<p>The last time I quit coffee for a long period time was around the end of college. It was really rough at first, but I started sleeping really well every night. I slept for 12 hours the first day, but I started to feel incredibly rested. I was able to just relax and read books. I felt more introspective and began to realize things inside of me that I had been distracted from. I felt more like me. I didn't have the highs that coffee brought, but I didn't have the lows brought by over-consumption, anxiety and sleep deprivation, headaches from withdrawal when I didn't have enough.<p>Of course, something got me back on it, I'm still drinking coffee, and it's even harder to quit now.<p>Here's a list of the long term effects:<p><a href="http://www.livestrong.com/article/97493-caffeine-longterm-effects/" rel="nofollow">http://www.livestrong.com/article/97493-caffeine-longterm-ef...</a>
