I have been off caffeine for 6 or so months now. I stopped cold-turkey before and went a whole year before joining my new job and free soda was too big to pass up. I have found that being with caffeine has actually helped me tremendously, I don't feel jittery anymore, I am more alert, I am able to stay awake longer (that one was weird to me as well), I was less likely to feel mentally tired at the end of the day, and my sleep has never been better (although I still have a delayed sleep phase ... luckily my work lets me work on my own terms =)) I also kicked the soda habit, about 3 months after I kicked the caffeine habit, and it has also changed me. I drink a LOT of water now, and overall don't mind the taste. I stay away from most everything that contains high fructose corn syrup, and have found that I have less energy dips throughout my day, and since I can keep my blood sugar pretty constant throughout the day I don't have any major dips where I feel like I am crashing. I used to be at the point where I would roll out of bed, drink a liter of Mountain Dew, then half a pot of coffee when I got to work, and at least another can or two of coke or something along those lines before lunch to try to kick-start my day. At some point I figured that I was dependent on caffeine much like a drug addict and that I did not like the fact that a chemical I was knowingly putting into my body was directing how I lived my life and what I bought for food.
