This is my first time posting, I read your post and got chills and ultimately started crying because it was so close to my experience.
The exact same thing happened to me on 22nd of July 2010.
I had purchased some chemicals from what sounds like the same vendor, the one who now has invite only customers.
What I purchased was "Buphedrone" However, what I got was certainly not Buphedrone. I have had experience with taking Buphedrone before and it came from the same vendor as the current bag I have. I was expecting the same mild-ish stimulant qualities I had experienced on it previously, but something went wrong, really, really wrong.
I injested around 70mg of the product, with thirty minutes, I had started to vomit violently, straining and gagging yet nothing was coming up. My vision went into a tunnel of darkness and I could no longer see my face in the mirror, I realise quickly that either, I have overdosed on Buphedrone OR what I was sold was some kind of psychedelic, it felt like a bad, heavy acid trip and it was only getting worse and stronger as the time went on.
An hour had passed, my pulse was out of control, I was sweating and frightened beyond belief. I had NEVER felt so intoxicated from anything I had had in the past.
I called my mother who came around to my house, to find me naked in a chair crying and sweating, completley disorientated and "psychotic" she later told me.
She called an ambulance, they arrive, and I freak out. I'm told I tried to swing at the paramedics, yelling screaming and kicking.. They radio the Police because they thought I was a "danger to myself and others".
Police arrive, more confusion and fear, I'm thrown into the paddy wagon like a freak, like a piece of garbage, they take me to the psychiatric ward at my local hospital under guard and locked in a glass room with a camera on me.
The nurses were not allowed to enter my room unless they were with the guards, I was treated like an animal, a wild, dangerous animal. I kept seeing the nurses and police rolling their eyes at me as if to say "oh just another fucked up junkie"
I was kept locked in that room for just under 24hours. And like agnetha, was not allowed to leave until I had the all clear of the psychiatrist.
I can confidently say that night, was most definatly the Worst night of my entire life.
Agnetha, I cried when you mentioned "the sun come out", I had said the EXACT thing, I remember felling, Im stuck in loop and time wasnt moving, all I need was the warmth and reassurance of the sun. Everything was dark, cold, looming and so scary.
I had remarkably similar experiences as Agnetha had, feeling like I had died, crossed over and was watching this drama unfold in front of me.
I have never been so fucking scared in my years of drug taking.
I'm left wondering what to do? I dont have the money to test this stuff, Ive emailed the vendor, and yet to get a response, they dont care.
I'm done with all RC's, I have been taking them for around two years, and this incident has truly rocked me to core of my existence, I feel so broken now.
That was my wake up call and frightening enough for me to walk away from it all.
Please don't be stupid like me, tread carefully, very carefully.
