Hate to be lazy and just state the obvious, but tea's a pretty good substitute. Get something black that suits your taste and you should be pretty set.
I do love tea, but that might be why I don't really feel the effects anymore. Maybe I'll go decaff, then start up again when overnights come around. I've been hooked on Rooibos tea lately anyway. Mmm tasty. Great, now you've got me wanting some. This clearly is all your fault, you know. Thank goodness for electric kettles. (runs off to make some tea)
