I remember reading and actually trying this with t3's back when i was a kid, but theres a way u can get rid of the acetimetiphon the only problem is im not sure if vicodin is water soluble or not, it worked with t'3s because because the codeine is water soluble and the acetimethpon is left over,but im not sure that vicodin is even soluble in water at all, but anuyways if it did work, which i would think it would u grind up ur vicodin and let it soak in some water, strain with coffee filter i think cheese cloth would let a lot of the acetimephon through but who knows, and then drink the remaining water, just becareful of dosage as its easier to mis judge when drinking it, just do what u would do normally i guess, pop a couple, but just grind up a couple.
