Dissociatives How much dxm to safely dissociate?

[IWantFentanylInMyShit]

I am very sensitive to serotonergic drugs and found that I get too stimulated from dxm polyisterex or however it's spelled. My friend got a bottle of dxm hbr. We cold water extracted the 0lastic version but this stuff i just said fuck it and popped 19 15 MG pills (285 mgs) he said that the hbr version should be less stimulating or seritonergic than the poly version. It's been about an hour and I can talk faster and colors are more defined but I don't feel dissociated. I know that dxm is stupid and bad. I just wanted to experience it at least once. It may be worth noting that it takes more than a gram of k to hole me and I have to do it fast. And that when I got my wisdom teeth pulled when I was younger, I was the last of my siblings to be put under and yet I was the first to gain coherency and they gave me a second dose cuz the first didn't put me under. Idk what the anesthetic was.
