exactraction of hydrocodone

[sands of time]

Ok, I want to do the cold water extraction of hydrocodone(the methode of crushing the pills and letting them sit in cold water for awhile, then straining the chalk and tylonal out) but I have a few questions. First, how much water should I use? I want to use a small amount but I also want to be able to drink it without throwing up. Lastly, how long should I let the crushed up stuff sit in the water for?
