Maaan, that's intense. I've tripped 7 times, never gone past early/mid 3rd plateau...don't know if I want to. I'm afraid of dying, quite honestly.
If I'm understanding your question...you don't need to do the cold water extraction on other DXM cough medicines, the Delsym extraction is to get the polystirex "off" so you get all the DXM at once...polystirex trips last longer and are weaker. Also, it (should technically) give you a more energetic high because less DXM is being converted to DXO.
Perfect trip music... https://www.youtube.com/watch?v=N1XqSZeV-_M"]YouTube - Team Sleep - Natalie Portman https://www.youtube.com/watch?v=A_K4wajiU-0&feature=related"]YouTube - Team Sleep - Formant https://www.youtube.com/watch?v=kX4-OMWCdCc&feature=related"]YouTube - "Sparrow"~ Beautiful Melancholy, by Adam Hurst https://www.youtube.com/watch?v=jDVFaheqQAg"]YouTube - Cavalleria Rusticana - Intermezzo
