I suppose it's technically an RC so... I recently OD'd on 4-Acetyl-Loperamide.
I was found lying in the street, unresponsive by a passer-by who phoned an ambulance.
I have wrote on 4-AL on this forum before, stating its obscene duration of action - first alerts are felt at 2-4 hours and build until... I don't even know, but I was out cold at T+24h.
In my system I also had approx. 1mg Diclazepam (Daily), 40mg 4-AL.
I could feel the overpowering nod around T+18 whilst on a bus. My last memory is of leaving the bus station and preparing to walk the rest of the journey home. I was found a few streets away either in the roadway or on the pavement (this was never made clear).
I awoke in hospital dazed, in WD to the extent that only a Narcan injection can bring forth, roughly 14 hours after I hit the ground (I was apparently placed under sedation and observed. It was treated as a suicide attempt (it wasn't) and I was later discharged after I made clear I had no suicidal intentions, nor ideation, and that I was in no pain (either I had been given analgesia in hospital whilst unconscious or 4-AL/a metabolite was providing such, as for the next few hours I had rather extensive pain in my right knee, right shoulder, right elbow, my neck and a cracking headache) and now, 24 hours later: I feel shaken, cold and generally sick, but well enough to post this.
In the past, I had used 4-AL with great success, at much higher doses, but in my stupidity I forgot to account for my massive drop in tolerance since then, and I doubt the benzo helped either.
All in all, my own stupidity is to blame.
EDIT: my notes show my dosage to be incorrect, this has been altered.
