Need help with liquid vicodin

I need help extracting the acetaminophen from my liquid Hydrocodone (Vicodin). Searching the net has produced no results. I have heard of the cold water extraction method, but Iâ??m not sure it will work on a liquid. Iâ??m not sure if the acetaminophen will separate from the mixture in cold water. I think the bitartrate is what makes it liquid because the only other ingredient is 7% Alcohol.

Hereâ??s the technical stuff
Hydrocodone bitartrate and acetaminophen elixir
Per 15 mL, Hydrocodon Bitartrate 7.5 mg, Acetaminophen 500mg

Someone please help me!

Lortab Elixir?
The bitartrate is the salt to which the hydrocodone base is bound. Hydrocodone, acetaminophen and alcohol are the active ingredients, the elixir also contains citric acid anhydrous, ethyl maltol, glycerin, methylparaben, propylene glycol, propylparaben, purified water, saccharin sodium, sorbitol solution, sucrose, with D&C Yellow #10 and FD&C Yellow #6 as coloring and natural and artificial flavoring.

Attempting to extract all the hydrocodone from a single bottle would be a pain in the ass, especially if you have no idea what you're doing. If you're looking to get high off it just take about 4 times the normal dosage, 30mg hydrocodone and 2000mg acetaminophen which is the usual adult dose of tylenol. Do not consume more than 3000mg acetaminophen at once, do not do this frequently.
