First and foremost I would like to thank my wife, Nicole, for providing me with a seemingly endless supply of love and support, and for putting up with my idiosyncrasies. I doubt anyone else could have coped with being married to someone whose idea of fun is spending hours in a library researching tripping off of cough syrup.

I would also like to thank Barbara Adeanna and Peter Zachariah Kramer who helped me proofread the FAQ and who took the time to tell me when I was confusing, unclear, or simply full of it. Additionally I would like to thank them for their support and encouragement throughout the writing process.

I would like to acknowledge Schering-Plough, Richardson-Vicks, and other OTC pharmaceutical companies, for giving me something to write about. How about bringing back DXM-only pills, folks?

The evolution of this document also owes a great deal to the participants of Usenet alt.drugs, alt.psychoactives, and rec.drugs.psychedelic, notably including P. L. and all the people who made hyperreal.org, the Lycaeum, and other drug websites what they are today. And to the hundred or so people who contributed their experiences to the FAQ, thank you; my understanding of DXM came about because of your assistance.

I'd like to give a moment of thanks to the one and only person thus far who has given me truly critical and negative feedback. I showed her feedback (and the resulting exchange of email) to a friend of mine who is a neuroscience researcher and physician, and my friend reassured me that this person's objections, although numerous, were also baseless. Still, it has given me something to think about. As hard as it may be for some people to believe, a big part of why I wrote the FAQ in the first place was out of concern for people's physical, emotional, and spiritual well-being.

Finally, thanks to my friend H., who taught me about DXM in the first place.
