I have had some interesting experiments before with Hydrocodone, I had a dental surgery and they gave me pain pills so I decided to experiment. I took the Hydrocodone waited till it started to kick in and then put on some binaural beats I had no goal in mind other than to see what kind of altered state it produced. I actually lost consciousness for a moment and found myself in the body of a Chinese man seeing with his eyes and experiencing his reality. His relatives he was living with shook me and I popped back into my own body. I have had many strange experiences with this particular recipe. I have tried other substances as well such as NyQuil and binaural beats which also produces an effect greater than the binaural beats alone .
