What you have is Tylenol 3. It's a mixture of Codeine and Tylenol, um, 30mg of codeine and 300mg of tylenol, i *beleive*. Anyways, there's WAY too much APAP (Tylenol) in those tablets to get high off the codeine without getting liver damage. Your best bet is to look up how to do a Cold
Water Extraction so you can filter all the Tylenol out and be left with pure codeine.
