If you love coffee, the best alternative to coffee is decaf. If you buy directly from a great roaster, you'll hardly be able to tell the difference. I'm not sure I'd be able to in a blind taste test (decaf if anything takes a little less bitter in latte form).
If you have a grinder, you could buy beans from any number of places online, like Blue Bottle. I'm lucky enough to live near a ton of roaster coffee shops that will grind bags for me.
