Read up on the stuff at Erowid. DXM is what you are looking for. Like they said, make sure it is the ONLY active ingredient. Robitussin Extra Strength Cough is a good one to look for. But definitely read about DXM before you do it. The stuff is unbelievably powerful in higher doses so you need to know how much to take and how to be safe while you are on it.
Ok, so I get the robitussin, now what do I mix with it? Or is that it?
