I've seen a lot of people suggest decaf. I go through periods where I drink a lot of coffee and when I drink none at all for months, and the only time I've ever felt withdrawal or headaches is weirdly when I've switched to decaf. Either way, I think it'll be difficult for us to predict how you'll react to cutting out coffee. While there is a lot of solid advice here, I think the best thing you could possibly do is pre-plan the stuff you need to get done in the next few weeks to ensure that any drop in productivity is covered. Either get ahead of it while you're on the coffee, or give yourself an opportunity to rest while you're weening yourself off and catch up later. The last thing you'll want to do is to do everything "right", and still feel like you're suffering.
