i found those lipton chai latte things that come in little packets worked for me, coz even tho they're not coffee they're still hot, sweet and milky so it was still satisfying.

carry a water bottle with you EVERYWHERE! you'll find that you'll drink from it just coz it's in your hand. thats how i quit smoking a couple of years ago and started drinking at least 3L of water a day, and i'm so so so much healthier for it today. Becuase your full of water, you wont want your coffee so much.
