how the fuck do you know what your BP is in your pulmonary artery whilst taking mephedrone 8)
Oh feck, now I feel rather silly... :-$
Ok, truth is I may have made an uneducated guess based on what I could feel and many hours of research but, no, you're right - I'm a tool for making that assertion.
What I **should** have said was: I could feel - especially when lying down - my pulse throbbing very hard up the left side of my neck. There was considerable discomfort caused by a sensation of pressure which worsened significantly when I lowered my head so my chin would touch my chest. I frequently had tingling/pain in my jaw, usually at the left-back. I experienced chronic and acute discomfort of varying intensity in my left chest area, usually below the breast bone or below the bottom rib.
It was impossible to lie on my left side, and even the weight of my left arm on my chest would cause sudden chest pains.
I was also getting seriously out of breath when I was sitting still - for example watching tv on the sofa before bed - and lying down would normally make it worse. Walking around the house would sometimes help to clear it a little; otherwise I just had to wait it out. I often ended up falling asleep half-upright on the sofa at 4 in the morning because I'd woken up in pain.
I'm an otherwise fit and healthy male, late 20s, average height, average/slightly muscular/slightly overweight build. I.e. nothing out of the ordinary and certainly nothing which would explain these signs and symptoms.
And yes, it scared the cock out of me

Since stopping the pains have gone, the sensations of pressure have gone, the discomfort has gone. I'm not "right" still, and I often find myself craving intoxication, but I don't constantly worry that I'm going to end up karking it suddenly, and things like running for the train don't leave me with my heart hammering away in my chest, out of breath, and sweating like anyone's business.
