Not much help, but I had a bad reaction to Venlafaxine.
I took my first pill at 10pm and woke up at 4am dripping with sweat to the point there was a pool of it on my chest. My heart was pounding at 140 bpm, I felt very dizzy, nauseous and like all my veins were about to burst.
Every heart beat was like a swooshing wash though my system - I could feel the blood rushing through me from my toes, fingers, lips, nose, ears - I could even 'hear' it!
I was rushing about the place like I was on speed, jabbering away incoherently, talking faster than my brain could keep up with making no sense at all.
I had red blotches all over my body and was suffering small spasms.
it was a very scary experience which my Dr put down to an allergic reaction to noradrenalin.
Needless to say I didn't take another one and it took me about three days to feel 'normal' again.
