I've had ginseng tea before. I really liked it, myself.
Though not as bad as that Frisian tea. Imagine very strong black tea (which I don't really like to begin with) with cream and rock sugar.
And that sounds quite good, actually. Though I like tea much more than coffee, so maybe that's why.
Also thirteen hours now, and the crash hasn't hit full severity yet. Probably going to sleep when I get home anyway, though.
