Hi, I'm a student at a Belgian university and I kind of ran out of time to finish learning my exam. So someone here in the studenthome gave me a mix of herbal extracts an caffeïne for the night. I think this was not the case, I've had tachycardia + increased heartrate all night long, also my limbs are a bit cold and numb, due to vasoconstriction (also blue knees and weird skin colour) My roommate told me I was probably given mephedrone! and actually I think he's right, it matches all the symptoms. My exam is tomorrow morning, I recieved the "booster" yesterday around 9pm. Can't fully concentrate and also I'm quite "amped up" if that's the correct word. I know I've been stupid but is there anything I can do about it, I've tried eating chocolate for the vasoconstriction, but eating is hard. I'm 21 years old, weigh 85kg and 175cm. I'm actually a dentistry student, and I know it's not lifethreatening at the moment, but I just want to be able to focus asap. Thanks in advance!
