i have been reading a heap on dmx/dextromethorphan and how it helps lower benzo tolerance as well as how it works generally. Man its a complicated drug, seems to be used by alot in higher doses to get high on, im not into that but look into its effects on NMDA and reversing benzo tolereance at much lower doses, also seems to help with narcotic tolerance so people can use less and get good pain relief. researching this is giving me a headache, if anyone has any good links for this it would be great.
