Ya know, it's been two days and the headache finally subsided. Went to dunkin and got a DECAF iced coffee w/ light cream, I believe there's about 5 units of caffein in decaf compared to about 45 in regular coffee, so the small amount did dull the pain. This morning it seems to be ok, though I'm thinking about a cup of green tea, just because I like it and we have about 9 flavors of it at my coffee shop (15 units of caff in green tea). BTW I forget exactly what the Units are, I just know the numbers!

Mmm:
green tea with mint
green tea with peach
green tea with orange, passionfruit, jasmine
green tea with raspberry
green tea with mango
green tea with blackberry
there's more, cant think of them all. Delish.
