Thats crazy that you mention that djaio, beacuse I have a friend who would report the same kind of thing from DXM. This guy never took a lot either, if he did more than about 300mg he would freak out too much and make other people have bad trips. But thats besides the point, what would happen is that he would look in the mirror for a long time and sware that his arms were shrinking or growing or that they had somehow become unproportional...he would sware that his arms were a differnt size for days after tripping. So, you're not alone. If anything, I belive that this is just DXM making you view things in a different perspective, like focusing so much on one part of your body that you notice it differently. I should note that this guy is probably 160 lbs and about 5'9" and would ususally only take between 250-300mb of DXM. I awlays thought it was pretty crazy and that he was imigianing it but now that you mention this mabey its a possible effect.
