It may not affect everyone this way....... However, don't wear white pants and NEVER trust a fart
The only time I tried DXM, the trip was okay, but the shits were bad. Didn't even have any guaf in it, just all the syrupy additives and stuff. It's not so much the fact that I got the shits that was a problem, it was the fact that the disassociation made it impossible to tell between a fart and sharting 8( Basically ruined a perfectly good pair of pants 8( Then, the dissociation made it so that I didn't even notice that I sharted for probably like 5-10 minutes. All in all, I wouldn't recommend the stuff, but there's definitely worse things out there.
