Depends on how much DXM you ingest, as well as your individual tolerance, body mass index, what form of DXM you ingest, how you space out the dosages (or not), etc. The effects are divided into five levels of intensity, or "plateaus", which I will explain only very briefly. First plateau is just nice, slightly different, things are more interesting. Second plateau is mostly just an intensification of first, but you may find it harder to walk, form sentences, speak, etc. and the dissociation will be more noticeable. Third plateau is by now completely different from first, with the dissociation becoming strong enough to make you care very little or not at all about things that would normally annoy, depress, or anger you, while making positive things far more fascinating. Your brain, body, perceptions, and everything will be quite liquidy. Fourth plateau is hard to explain. Suffice it to say that while on a fourth plateau trip I get so dissociated that I feel no connection to my identity anymore, and forget my name, what it means to be me, etc. I had to try hard to understand the existence of other people, because their names and faces just didn't seem to have any meaning. My consciousness felt like an endless, rolling ocean. Plateau Sigma is achieved through a dosage regimen which leaves more DXM in the body as opposed to DXO, what most of it is usually converted to. This creates an experience that is completely psychotic, with powerful hallucinations and delusions, mimicking schizophrenia. Plateau Sigma is NOT the same thing as other psychedelics, and is far more likely to result in a horrible, terrifying time than a fun trip.
