obviously your paracetamol to sauninginal ducts ratio is gonna be waaaaaay out of whack. generally speaking the equivalent of 2 drinks will not cause serious harm to your kidneys or to your ducts, though it can have some symptoms like fever/hotness of the face from swollen ducts/kidneys, bloating, pissing, loss of balance due to constricted arteries decreasing blood flow to your head and ears.
so if you have any of those or the whole pissing brown thing, see your doctor, and quick.
