Well I tried the DMT last night, and.... it did jack diddilly shite

. I came in a bit pissed (well a lot pissed, evil stuff alcohol :s), and decided to crack out the DMT. Split what I had into 5 piles (250mg was in the bag), made a little foil cup, placed 50mg into the cup then heated the bottom of the foil and sucked through the tube of a pen. Nothing. Well not nothing, there was a strange, slightly euphoric feeling, and a small visual change, but apart from that, nothing. I proceded to load another 25mg (just in case I lost a lot in the burning process), and still nothing.
Not quite sure why I got little out of it... Been considering it, and at the time I was considerablly pissed, I'd had a small amount of GBL (most probably out of my system by then), and had kratom in my system (then again I always have kratom in my system; intentional addict). All that, and I take 45mg of mirtazapine, 200mg of 5htp, 500mg of rhodiola rosea extract, and 1800mg of oxiracetam a day (the oxi is only a recent thing).
Now I know antidepressants can effect psychedelics, but they surely they shouldn't blunt them out completely? All together I must have smoked at least 70mg. Perhaps it is all the prescribed and self prescribed medication I'm on, perhaps the alcohol blunted the effects and perhaps my method of smoking was flawed, but surely I should have got something out of it?
Ooo as a side note, it really smelt and tasted a lot better than I thought it would, not quite sure why as it is definitely a chemically sort of taste? I actually ended up smelling the pen tube I smoked it through when I woke up this morning lol
