Nah not on MAOIs or SSRIs, though I did take a tetracyclic antidepressant (mirtazapine) until very recently and still had the drug in my system when I last used DXM. That was probably a stupid idea (tetracyclic's can still lead to serotonin syndrome from what I hear). I was actually wondering myself whether or not that affected the intensity or general feeling of the trip.
Not counting serotonin syndrome for a sec, do you think being on antidepressants would effect the intensity of a trip (as in make it less intense)? Because I didn't get any opened eye visual effects (like tracers) during my last experience and just felt fairly drunk.
Next time I use there won't be any antidepressants in my system though.
