I gave up caffeine last July -- I had decided I really didn't need it. I was surprised that I didn't really get many headaches or suffer any withdrawal. But after I returned from summer vacation, I found I really wasn't as productive as I had been before. Before, I could maintain two blogs, occasionally post on MR, and work on larger book writing projects. But after giving up caffeine I was having trouble even maintaining one blog, let alone get any other work done. My days were seeming to waste away faster and faster. So today, I decided to try reintroducing caffeine into my life (actually half-caffeine, half decaf, which is what I was drinking before). Right now, I'm halfway through my first cup. I've got to say, I feel great. What's your story with caffeine? Is it indispensable? Or do you have other ways to stay alert/motivated? Now I'm going to write that blog post I've been putting off for three days. I'll be back in a couple hours to check, so keep those stories rolling for me!
