DXM is a dissociative like ketamine. Very good for depression for some. Dunno if like ketamine, it has an after glow affect it might. Once you take one big dose you should feel a little better a week after or longer than not taking it. (That's just my uneducated information).

I don't know what other ingredients are in that cough medicine if it has paracetamol or something stay away don't even drink at all that stuff it's terrible. RESEARCH the ingredients for knowledge if you have tendencies of suicide if could seriously mess up your liver and make your life much worse.

DXM is not that addictive. I think you are using your past to justify and convince yourself that it is OK with depressive thoughts to overdose.

DXM has many dangers such as brain damage if you take it too much. There are other drugs (psych meds) that can help with your depression.
