I've also been off of caffeine for about two years, for a few reasons (anxiety reduction, desire to be free of chemical dependencies, and especially sleep improvement). It took me about three weeks of depression and lethargy, but was totally worth it. My sleep especially is much-improved, and I'd say that my anxiety levels are generally lower. The main thing is that you need to get enough sleep at night. If you're interested, I found some support on reddit, http://www.reddit.com/r/decaf http://www.reddit.com/r/decaf.
