I dunno. For me, the side effects were just too pronounced. Nausea, itching, deep confusion, being in such a dissociated state for so many hours, etc. I can gain everything and much much more from a good dose of Ketamine than I ever can from DXM. Not only that, I'm not stuck in a dissociated state for hours and hours.
However, I must admit I have had one powerful DXM experience that changed my perspective of the substance. Until the next time I tried it.. and the subsequent trips that followed after that.
On my only beneficial trip I ingested 600mg on an empty stomach, with my ex-girlfriend. Purpose of the trip? To try to find a reason on why I'm so prone to addiction (Yes, weird I know..taking more drugs to find a solution to the problem I have with drugs... 8( ). Anyway, while I didn't find an answer to my question or come up with any sentence that a 1st grader couldn't come up with. I did have an extremely intense experience, one in which my thoughts were beyond contemplation and once I threw marijuana into the mix..my god..where the fuck was I? Didn't speak a word to my girlfriend at the time. However, had very impressive Closed Eye Visuals (the open-eyed visuals were shit) and what are called "mini-dreams" by many, which consequently brought back many childhood memories for me. Things I had long forgotten.
Anyway, my later experiences with the drug were quite honestly boring, with the drug lacking the total dissociation Ketamine brings and having all, plus more of the ghastly side effects of 5meo-dipt.
