Have you ever tried DXM on lower/moderate doses? If so, have you had a clear intention set about a particular issue that you wanted to address? That makes a big difference.

Only because DXM is being abused a lot and the fact that you can only get it in the form of cough syrup in the US doesn't mean that there is no way to use it more responsibly/purposefully. Also: Effects very much differ from person to person. In fact: most people don't seem to like it / have negative (side) effects.
